If you're an old-school type who's read Dante, a proper hellish eternity might be confinement in a lake of boiling blood- that actually sounds pretty good compared to what's crossed my mind today.
I think a good-and-proper satanic torture (for me personally, at least) would be having to spend the rest of eternity on the phone talking to my mother while trying to explain how to do something simple on her computer- logging onto my Photobucket account with my username and password, perhaps, or maybe assisting her in trying to find my YouTube account so she can watch a video I've uploaded (where we start running into problems with Google, and then things go downhill from there)- I realize a program like LogMeIn would help, but I'll have to wait until the next time I'm in NY to install it (wow- explaining how to set up LogMeIn to my mom over the phone- shoot me now...)
A computer screen turns this reasonably intelligent woman into a blithering idiot, and it takes every ounce of will to keep my composure (which, admittedly, I sometimes lose). If I have to hear, 'Everything on the screen disappeared and I didn't touch anything' one more time...
Yes, that would be a good-and-proper punishment worthy of making me walk the straight-and-narrow in this life- the thought of it fills me with dread.
What's your personal hell?
