Like make my mother go to the hospital so maybe just maybe she'd still be alive.
Talk to you the first time so that I wouldn't have made both of us miserable.
Gotten the guts up to tell you sooner so I didn't have to suffer from Kevin any more than what I did.
Gotten up and played outside more when I was younger so I wouldn't have gotten as huge as I am now.

Just a bunch of other things like that.
