I was very drunk last night. My mum came through at night and said we will be having a chat in the morning, I asked why and she said because I've been drinking. What can I say?
Irregardless as to your age - IF you are living with someone else and they pay the bills it is Your responsibility to follow rules and be courteous. If you are breaking rules, not being courteous it is a sign of immaturity. Immature people have no business drinking - someone WILL be hurt. My advice is to tell your Mother that you showed lack of respect and acted immaturely. Showing and receiving Respect and being a mature person are things you value enough to not pull a stunt like that again
When she says .. 'we need to chat' especially when it pertains to your behaviour .. There IS nothing to "say" as THIS is the time to listen .. Not talk.
You need to listen to your parents. Second, I suggest you look at the big picture: a lot of young people die in car crashes do to DUI. People care for you. Care for yourself
