Annoyed
I hate it when people make arrangements with me and cancel them, It really gets me annoyed. I realise that it isn't their fault and that other things have to take priority but with some people it happens practically 2/3's of the time, I am meant to be meeting them. I also really annoys me that most of the time people don't bother to tell me that they are canceling doing something until I contact them. Isn't it just polite and thoughtful to just quickly write an email to say 'I am really sorry but I can't do this because something has come up', instead of doing that when I am making arrangements.
