I'm fully prepared to be told I am BU based on DS1s looks he gave me
but it's been bugging me.
DS2s girlfriend came over late last night, about 10:30ish and didn't say anything as she stood in the hall whilst ds talked to me then ran off upstairs without saying a word. She then came down at almost midnight in her tiny pyjama shorts and Tshirt to say hello and apologise for not saying hi almost an hour and a half ago and said she had to go upstairs and get changed because she was freezing. Yes I'm sure she was so cold she couldnt pop her head round the door and say hello because she had to change out of her freezing cold coat, jumper and leggings into her shorts. 
I wasn't expecting her to come sit with us and chat for hours, no. I knew she wouldn't because me, DP, DS1, his girlfriend and DD were taking up the 2 sofas and she's a total bitch a bit fussy when all the sofas were taken up and expects someone to sit on the floor so she can sit down I just wanted a hello.
Then an hour ago she left for college and didn't even say goodbye. I didn't know she had left until DD said her ped wasn't outside anymore.
I just feel it's rude.
Also, I don't dislike her. I understand my post might look that way but I just needed to vent and she's doing my ducking head in at he mo.
