When I was a kid I set my own neighbors clothes on fire when they left them on the line

I was like 11 and there was this old lady who would leave her clothes out on the line all day every day and it was super hot in the summer so I decided I'd set her clothes on fire. So every time she put clothes out I'd take them back in her house and set them on fire. The flames weren't all that high but it was mostly towels so it looked like a lot of flames. Then one day her daughter was home and I got scared cause I didn't want to get in trouble but she just laughed it off and didn't tell her mom.
