Being an adult is not just about doing what you want. Do you work/pay rent to your mother if you are still living at home? Do you do any of the many chores necessary to help run a household; grocery shopping, cleaning, etc. If you are living at home with your mother, it is rude to ignore her, like she's just a boarder in her own home. I would definitely ask what I could do to help with the household and would ask when I went out if I could stop and bring anything home that was needed. If you do not want to like your mother, then move out of her space on your own. If you cannot afford to move out then you cannot afford to spend all your time playing with your friends.
