DS1 (4) and I went swimming this afternoon. It's a swimming pool of a members only gym and members' children are only allowed to swim between 2pm and 5pm. So it can get quite noisy and splashy with all the kids but that's only to be expected.
As it was, there were hardly any other people there this afternoon probably due to the nice weather. DS1 was being a bit noisy and splashy but was genuinely enjoying himself and playing in the water (he's only just learned to swim)
There was an elderly lady swimming on the other side of the pool in a section cordoned off for people who want to do laps so DS1 was definitely not getting in her way or splashing her. DS1 was talking to me about something when she raised her head and said in the nastiest tone possible "shut up!". I couldn't believe it. I said to her "don't tell him to shut up - if you want a quiet swim then don't come in the children's swimming time" or words to that effect.
But in hindsight, I'm fuming and wish I'd said something a bit harsher. Poor DS1 - he looked so shocked and dismayed and he was being such a good boy and trying his best to swim well.
