All those people with prams getting frustrated with slow walkers in front of you. Where were you actually in a rush to?
Usually towards the bus-stop, train station, nursery or just trying to get from shop to shop at a reasonable speed, before toddler wakes from his nap. It's not 'slow walkers' who frustrate me- everyone is entitled to go at their own pace. It's people who drift slowly down the middle of the street/precinct completely oblivious they are blocking others. It's good manners to be aware of others around you, step aside to faster people pass, keep to one side rather than obstruct others. When I walk with toddler on reins I'm aware we're very slow and dithery (she likes to stop randomly to look at things) so I'm careful not to block the street or trip people up.
So, usually nowhere of actual importance then? I was expecting sensible replies like running late for school/work/hospital appointments which of course doesn't make it acceptable but does make it understandable. Some are accidents of course. Others are just examples of people being full of their own self importance. Instead it appears people are just getting pissed off at other humans who don't gave the dexterity to dive in to the nearest shelves to allow you and your buggy to go by.
Oh, and bollocks to it was lighthearted/only joking.
OP: AIBU to want to ram into any human that doesn't clear my path in 60seconds?
MN: Of course you bloody are.
Others: I think OP was only joking/so was I/ I'd never ram anyone, despite a few delightful individuals happily confessing to doing just that.
If you're happy enough to do it then be happy enough to take the consequences when the next poor unsuspecting individual who didnt see you coming, doesn't take it lightly and decides to return the favour by taking the pram you've just rammed their ankles and shoving it up your bloody arse.
