["I'm having such trouble with a co-worker.  She has no manners at all!", 'really? like how? what she do?', 'I hurt my foor a few days ago and have been limping a bit.  So she goes and calls me crippled at first and she keeps calling me slow and laughing really hard.']
don't worry, with people like this karma hits them very very hard, and they get what they deserve
I injured my foot a couple of days ago (muscle strain).  Now my co-worker keeps calling me slow and laughing about it.  When she's not calling me crippled instead.
