AIBU to get irritated with someone letting their kid play an 'educational' game on a smart phone on the bus

[AJ65]

It's not the game itself, more that everyone on the bus was subjected to the noises, first the basic sentences, then the clattering jangling nonsense of the 'rewards'. I'm all for educational aps, but did we all have to hear it?

Stuff like this annoys me too. It’s sound off, ear phones or no device. Simple really! Unfortunately some parents seem to think the whole sodding world wants to hear Johnny or Tina’s game

I hear you.
I am sitting in a hospital clinic and the woman next to me is practicing her choir music. In a tuneless warble.
It is doing my head in.
