Of course in some situations they do.
But seriously, I read a thread where someone organised an event and invited her friends = controlling.
An OP gets flamed and has goading comments thrown at them = angry.
A flaky friend who generally just cannot be bothered = has anxiety.
I see the anxiety one especially time after time (even when the OP states that they don't), sometimes some people are just selfish and lazy.
I remember one thread, a woman said she was tired of inviting this woman (an ex-housemate) because she always cancelled, the OP said she had a huge house party when it was her birthday was always going for weekends away to party with friends - yet cue the anxiety comments.
