in all seriousness, i haven't responded to many of your posts, so i can't ALWAYS be mocking you....
i am fairly sarcastic. however, i try to be lighthearted with it and rarely mean anything insulting. unless, of course, i do mean something insulting. but i usually try to make it very plain that i am being insulting.
that said, i am pretty straightforward. in the case of the post above, my sincerity may be a little to blatant: i would love to see you do something wickedly funny to get one over on rick (or anyone else for that matter).
i think you may be sensing that i have been a bit stand-offish, actually. and i have. i usually am with people that i don't know. once i get a bit of a handle on the person and their personality, i open up a bit. on the flip side, i am genuinely hurt when someone that i consider my friend takes a pot-shot at me with the intention to hurt my feelings. so, there you go.
in short: if i am mocking you, it is in fun. generally speaking, i don't mock people, except myself (i mock myself all the time).
cheers.
