I know exactly what you mean, Shaina. Both my HMs have changed considerably since I first got them. Neither is as attractive as they were, and they've both gotten lazy and less entertaining.
Considering I bought them for their looks, as well as my entertainment and amusement, I feel somehow cheated. I know it's not their fault, but it's certainly not mine.
So I feed and maintain them and admire them for what they are. And every now and again I sigh and look at old pictures and try not to resent them, or feel guilty because I do.
Thanks, User. Perspective always helps.
