I think you'd be well within your rights to be cross if someone tries to take advantage of your good nature. Screw being "a sport," I'm very much against most forms of joke phone calls and practical jokes. If someone expresses dismay because they've just been told their mother is dead/they've lost their job/they're being deported/a plane has fallen from the sky/their fiance has broken off the relationship/etc I don't find that funny At All.

I find lots (and lots and lots) of things funny, but not that. Grrrr.

Sorry, got a bit ranty there thinking about commercial radio pranks. I've been unwell the last two days and am getting cabin fever.
