Event - My son and I were at the park and there was an ant hill. I remember when I was a kid pouring gasoline into them and lighting them on fire and I thought my kid would get a kick out of something like that. I had a lighter and dumped it in the hill and lit it - little ants running everywhere. My son was jumping up and down, thrilled. That's when I realised I did a bad thing.
Apology - I shouldn't be teaching my kid to kill things - or even play with fire probably. Hope I haven't scarred him.
