Drives me up the wall. Like they have the franchise on being busy and then every time you encounter them, all they do is talk about how busy they are and list everything they have got going on in their lives. This is usually in conjunction with a 'we must catch up properly' or 'I'm sorry I've not been in touch'. Erm, no we mustn't because you bore the tits off me and we had a cuppa only two weeks ago when you bored the tits off me then too.
Rarely ask how I am doing or if they do, as soon as I've replied they immediately link it back to how busy they are.
If you are that fecking busy then do less stuff or stop moaning about it but at least try to understand that your life list is not any more important than anyone elses. There, rant over!!!
