Addendum to last post:

I missed one excuse for angsters, and it really needs adding:

It is naturally also excuseable to actually anget all over people if you HAVE actually had a sufficiently horrible trauma.

Beware perspective! Guy you met a week ago leaving you? No excuse.

Hubby of 10 years running out? Excuse.

Person said something bitchy about you? No excuse.

Person attacked you with an axe and cut your legs off? Excuse. Besides which, I can run away.
