lonely?

i went out to my grandma's house today and got my nails done. i stayed after my grandma was done doing my nails to watch the movie "the game plan". i think that i've seen the movie before, it seemed familiar to me. my mom asked me if i was ready to go back to her place about 5 minutes into the movie and i told her that i was watching the movie. i seen my grandma's face smile a little when i said that. i think that she gets lonely at her house sometimes. that's the case or she likes having me around her. i can understand her being lonesome, my uncle and grandpa are both gone and she's only got my other uncle and his girlfriend to keep her company. my sister said that they act like my grandma's house is their house. i didn't see them acting like that was the case but both of them stayed away from me and were both in the other room when i was there. my brother lives with my grandma too and he doesn't seem to help out around the house.
