! = 'oh my, I can't believe you said that' OR 'that's rather amusing'
x (when placed after an 'offensive' comment) = 'only joking, love'
x = 'you sound a little sad, have some love'
... = 'I've run out of things to say on the subject' OR 'go on'
. = 'well, ok, if you say so...shut up'
? = 'you make no sense' OR 'hello give me some fucking attention'

Apparently I am confusing to talk to on MSN.
