Ok admittedly I'm possibly much older than you lot out there, so I might need to call a taxi but here goes.
It's just after Christmas and I live in a tiny village with one coffee shop. We attract loads of families walking on weekends which is fine. But of course the shop is heaving. Again it's OK.
My friend had an awful Christmas day with an adult autistic son, a missing pet cat = son meltdown and she just needed a shoulder. Could not go to either home as hers contains adult son, mine contains old husband watching Wheeler Dealers on full volume.
So we luckily find our usual table and get a coffee ....okaaayyy I had cake as well.
A group of grandparents, parents and a toddler arrive and sit next to us..still OK.
Now I fully understand toddlers are noisy, I get it. But to keep the already overexcited child entertained they then began an interminable game of peek a boo, who's got your nose, piggy toes etc, which then turns a chatty chirping child into a screaming harpy , creating such a noise that no one can speak. My poor friend was almost in tears from the stress.
Eventually I nicely said (yes I can do nice) that while everyone understands children's noise, could they please not add to it by encouraging her.
Seems walkers from the big city find it difficult to take polite requests. Enough said.
So AIBU to just expect a parent not to encouraging loud noise in an already packed out Cafe or us it open season on quiet breaks now.
