There was a classic multi substance addict hanging out in the park yesterday. Can of cheap beer in hand, gaunt, toothless, incoherently chatting to themself, I don't know their name, so let's just call them LA. LA had a speaker playing fairly loud music, and my 3 year old and her friend went over and started dancing to the music and running rings around LA. LA seemed to genuinely be enjoying the fact the kids were enjoying the music, so it was kind of harmonious. Me and the other mum kept trying to tell the kids this wasn't the right person to play with, but they kept running over. Eventually I went over with the kids and I really didn't feel comfortable getting too close to LA, and didn't want to strike up conversation because they were just to in their own world and I didn't know what would happen if I tried to chat. So I told the kids we were going to play musical statues and took them back to where the other mum was and played a game with them there and that kept them from running back to LA. I genuinely wanted to have a word with LA to say I don't want my kid playing with a stranger who is clearly not sober and could they listen to their music elsewhere. Am I being unreasonable? And what could I have done differently to keep the kids safe and not be a jerk in front of LA?
