Constant incorrect use of the progressive tense for "to sit" and "to stand" is turning me into a monster

[applesauce1]

My professional background includes copy writing and teaching, although these issues can be traced back to childhood when I had form for occasionally (and very rudely) correcting the grammar of my friends' parents. I don't know what is wrong with me and I want to change.

I can't stop noticing the frequency with which people use the incorrect progressive form for "to sit" and "to stand". When I hear friends and colleagues say, "I was sat there" or, "He was stood at the bar", it completely distracts me from their anecdote. I start mentally musing that by using the passive form, it changes the meaning of the sentence. What a horrible dick I am.

I know that I need I let it go. I need to stop noticing. There was a recent thread about aeroplane seating that I struggled to read due to the constant mentions of, "I was sat".

I don't want to be this way. I'm not a teacher anymore. Of course, I would never bring this up with anyone, but I want to stop noticing altogether. I don't want to be this horrible person.

This isn't the only common mistake that irks me, but it has the greatest effect.

Please help me.

Same here, OP. You even see sat and stood in advertisements and newspaper articles now. Gives me and DH the rage!

"didn't use" is correct. You even see "didn't used" in published novels by respected writers and that is a totally unacceptable mistake.
The mistake occurs because we only ever, by definition, use (completely different verb with different pronunciation!) "used to" in the past, so its infinitive form (used to make a negative past- didn't + infinitive) gets a hyper-application of the -D ending rule.

I think it's also compounded by the fact "didn't use to", when said quickly can sound like "didn't used to"

I am also driven mad by
‘And she turned around and said’
What is all this turning around?

@redskittleorangeskittle Kids with SEN must have been at such a disadvantage in your classroom

Primary school teacher and grammar Nazi here. It’s not the same when children are making these errors, at least not for me, as children make errors as part of learning all the time. For instance, before they learn the correct past tense of ‘teach’ they automatically use what they have absorbed about English grammar to say ‘teached’. Our job is to help them learn correct English. I don’t get irritated by their incorrect English, because they are still learning. However I do get irritated when my colleagues model solecisms such as ‘Well done Jack, you done amazing’.

It’s slightly concerning that you have such a narrow view of what constitutes SEN, which often has nothing at all to do with grammar.

Our local Costa has a sign asking customers to wear face coverings ‘unless you are sat at a designated seating area’.

I'm a bit late to this discussion, but may I add using the singular when talking about many (and vice versa). It has started to infiltrate everywhere, even on TV and Radio

Example

'There were a few people in the park earlier, but there isn't any now'.

The sentence is saying that there was more than 1 person, so it should be 'aren't any now' shouldn't it? Surely it would be just as wrong as saying 'Jack and Jill is going up the hill'. This is what I was taught, please tell me I'm not getting irrationally angry at something that is actually correct?

So many things make me grit my teeth when I hear them, the other one that really annoys me for example is, 'I dropped it on the floor', when someone is outside. Floor is inside, ground is outside (obviously excluding correct terms like 'forest floor'

Agree with @TheSeedsOfADream that sat/stood are dialect variations rather than errors. See also done instead of did.

It may annoy you to hear them, but to my mind this is preferable to the days just two generations ago when children were forbidden from using their own dialects in schools as a result of which many words were eventually lost.
