am i being selfish?

i'm at my mom's house right now and we're going to my grandma's sister's wedding later, i'm not sure if we're going to the actual reception but i don't think so because my sister said something about them getting married through the courts and that we're only going to the reception. i'm starting to feel annoyed with how selfish that my grandma and mom are being with smoking in the van that i bought. everything that they do while i'm at their house seems like it has to benefit them in some way or they won't do it. maybe i'm just being selfish though but i do think that i have a right for them not to smoke in the vehicle that i bought and is used only when i'm home.
yesterday the old site supervisor (of the asi/housing site where i live at) viaited the apartment where i live. he was really surprised on how good he said i looked and sounded. it's funny because the night before when i was praying, i prayed for him to come back to the apartment where i live and also for him to become site supervisor of the asi/housing site i live at soon. he came as i was walking with my walker and said he was amazed on how good i was doing snd how nice my apartment looked. i was glad to see him, i told him that i still needed to figure out what i was going to do as far as schooling and careers go, he told me that i still have a long time to figure that out because he said that he's 38 (or somewhere around that age) and still going to school for nursing. i think i wanna try to get on my feet again before i make any decisions. maurice and i both said that we missed colby and he should come back to being supervisor of where we live. my grandma also said that she thought that she liked the way things were ran when colby was supervisor of the program that i'm in and she thought he kept it going.
