Molly LOVES me, she's a little snuggly nerd with me, and quite frankly, I thought she was that way with everyone when we originally got her. But apparantly she runs from the other people in my family, and rarely, if ever, jumps up on their laps to be patted. My sister feels particularly insulted, because she was the one who rescued Molly (Molly was stuck in a tree for 5 hours before my sister found her and got her down, and then took her home), but I suppose it's because I'm the one who feeds her and gives her water and, I dunno, speak her language better. I'm not sure how to say it, and my mind isn't at it's peak anymore (it's 3:51 in the morning, lol), but I act gentle to her, and my hands move slowly, I blink a lot, and I tend to mew at her and sometimes give snoring snorts, my version of purring, lol.
Buffy seems to prefer me over the rest as well, but not to the degree as Molly. I raised Buffy from a 4 week old, and she did hold me in a higher status for the longest time, but for the past year she's turned into a loner. She still loves people and will seek affection from everyone (and will hang out with me the longest), but she's not the love-bug she used to be.
Willow definitely prefers my dad. With everyone else, she can take it or leave it (unless you have food, then you're suddenly your favorite, until the last bite is gone and then she doesn't care for you anymore). When dad comes around, she starts rolling around by his feet, emphasizing the plumpness of her body (it looks that way, really, because she's actually quite thin, but she has a thick long coat which can be misleading). And sadly, to me, she doesn't prefer me over the rest of the family, after dad. She treats me the same way she treats my sister or my mom. Oh well, lol
