So I'm sat on a very full bus and there was a lady with a young toddler in a pram. I can see where you think this is going... but no, not a bus/wheelchair debate, don't worry.
So the toddler was clearly upset at something and was crying and groaning. The mum was talking to her, pulling faces, rocking the pushchair (as best you can when the safety lock is on) to settle the toddler. Tbf, she looked knackered and at her wits end. When she pressed the bell to get off people cheered. As she was pushing the pram down he aisle one man yelled "thank god! Keep them indoors if you can't control them". She looked so hurt! I was raging! The poor woman was trying her best and it was a toddler for god's sake!! I sort of said loudly and generally for them to pack it in but was drowned out by the cheers and giggles from everyone. I'm still annoyed!
I find the death stare works wonders in situations like these. My response to the wanker who told her to keep the baby at home would have been take your own damn advice you selfish prick. I'm not very good at keeping my tongue when I see things like this because I was that parent at one point!!
I was on a packed train once when a man was driving the whole packed carriage mad with his loud business speak conversations all on speaker. He went to the loo and someone threw his phone out the window and everyone else cheered and nobody dobbed in the man who did it when he returned to no phone and lots of stifled giggling etc. It made the newspapers. So l can believe everyone joined in as it only takes one to stick head over parapet and say what a lot of people are thinking. Unfortunately some people are always going to get annoyed whether it's a loud phone conversation or a toddler crying as both can be quite grating in a confined space.
What nice people I know whiny kids can be annoying -but I also remember the awful feeling of everyone staring when mychild had a cry/tantrum/meltdown in public. I would say the vast majority of us have experienced it at some point. I think some have selective memories/a stick up their judgy arse. I would have been massively tempted to give everyone the finger on the way off. Not terribly clever but satisfying.
