@roger,
Right, that was my question!
Anyway, $125 ... sozlet (age 11) just meandered by and I asked her.
- Chores (big chores)
- Taking away "screen time" (TV, computer, video games)
- "Striking when he's not thinking about it." I didn't get this at first, she explained: imagine that a friend calls and asks him to join them for an awesome expedition to a water park. He asks you for permission, and you say, "Nope... because you lost the bet." That seems a little mean to me! (She says "but that one thing is worth $125, I think." "Or maybe more," she adds.)
I haven't really come up with anything better. I was thinking of some sort of positive donation of time (since he doesn't really have the money), like working at a food bank or something. BUT, I don't think it's good to link that to a punishment. (Sozlet did it recently and loved it.)
