Maybe ask me what I'm doing, before deciding that I'm going over to your friends for fish and chips! Just because I dont go out that often, doesnt mean I dont have a life! You treat your daughter, my sister, more like an adult than me, even though I'm the one with the full time job, working my arse off, while you give her money to go out partying every night.
Talk to me when you have your priorities in check.
