AIBU after being reported for apparently targeting a member of staff

[Vintageshirtsearch]

OK no one is going to believe this to be true but I need to share it. I was spoken to today by my line manager as I've been reported in our 'call it out' policy. I made a member of staff feel targeted and picked on.
I bet you won't be able to guess what I did that made them feel so bad.
It's so crackers I actually thought my manager was joking.
Anyone want to guess?

Spoke to them about time keeping?

Offered to make them a cup of tea?

Called a man in a dress He/Him

Pronoun issue?

Talked to them stood up, while they were sat in a chair?

You asked them not to spend twenty minutes of every working hour making tea for themselves and twelve coworkers, only for them to complain and tell your boss you told them they’re not allowed to make themselves a cup of tea?

No one is right yet.
I don't want to be annoying and drag it out but it's so much less than anything mentioned so far
The complaining person is 30 and I am 50 so both adults.

You looked at them funny?

Did you say hi how are you?

Just. Tell. Us. We're not four year olds in a guessing game.

Said 'good morning how are you?'

Said something like "oh have you had your hair done?"

Did you ask them if they'd had a good weekend?

You asked them a mild personal question as small talk?
You asked them in a meeting what they thought about something?

Did you ask them to guess what task you’d like them to do next?

Used caps in an email?

What is it?

Did you use a full stop in a message?

either tell us or get in the bin x

Irritated them by playing a dull game?

Forgot to say please?

Oh come on, please don't keep us in suspenders!

Are you doing anything nice on your holidays?

During a coffee break, another staff member said they thought Taylor Swifts wedding was over the top and a bit ridiculous. I said "yeah I agree" the complainer said it was to keep it private and I laughed and said "in madison square garden" the other staff member said he didn't get the hype over taylor swift and I said I didn't either. End of conversation.
Apparently this deeplynupset the complainer as they love taylor swift and they felt mocked.

Asked them what they were doing for lunch? #triggering..
