We know 3 is true, so I'll say 2 just because I don't remember you mentioning flatness before and I'm too lazy to check.
1) I didn't learn to swim until I was 11 although my mom tried getting me lessons earlier
2) Despite being in Cub Scouts for 2 years I've never been camping
3) I used to mark pages in Choose Your Own Adventure books to make sure I eventually got to read every page
Nope, 2 is true. 1 is the lie, I see my mom's boobs all the time, even now. When I was a kid I would sit on the closed toilet lid while she was taking a bath and we'd just chat. Mom was a great example of how to be comfortable in your skin.
If 2 is true, then 1 is the lie, because who
didn't mark pages in CYOA books?
Jaydub, I thought at first that #2 was a lie, because I didn't think a five year old could throw a brick with enough force to shatter a window. But then I thought about five year olds I have known, and reconsidered this position. So now I think 3 is the lie, because it seems like the kind of thing you would spare your friends, assuming you liked them.
