I grew up as the only girl, with 2 older brothers 5 and 6 years older than me. What 1 didn't think of to do to torment or tease me, or trick me into doing,...the other 1 did. That was OK though, I learned really quickly that if I didn't cry right when they did something, but instead waited to cry when Dad walked in the door from work...I ended up with the last laugh, because he never asked when or how long ago they did it. They still, all these years later, remember how that worked with Dad.
I know the feeling. My sister kicked my .... until I was about 13, then she sicced her husband on me. We were a loving family.
