DM has a habit of this. Phone rang at 8:30, my Mum wanting to wish us a Happy New Year, however we were still in bed, having not got home until 1:30 this morning.
It woke all three of us up, but went to the answer machine before I could get to it. Just managing to doze off again and she rang not 15 minutes later.
My B'day was a Sunday this year and she rang at 7:30 in the bloody morning to wish me happy birthday! Why?!?
It's the same on an evening, which I will admit isn't an issue now. She knows we get in from work and sit down to have tea around six. (We've told her multiple times) However at least twice a week, she rings at bang on six. We just let that one go to the answer machine every single time, but she never gets the hint.
Sorry more a rant than anything, but AIBU?
