Skills/hobbies missing on Likes and Dislikes

I think there might have been less annoyance if they'd labeled it "Skills" rather than "Activities", because it's obviously Skills. And it doesn't work that well. I had a goofball Sim dislike Mischief, but she went ahead and pranked the toilet anyway. The main thing is that it seems to raise fun for skills your Sim likes, which is good for things like Handiness. Playing chess and reading already raise fun, which might be why they left them out.
