I'll probably start giving when I feel I've wrung every last cent of value out of the cap and gown the law school forced me to purchase for graduation. Haven't stopped enjoying it yet, though.
Seriously, this might sound petty to some, but those nickel-dimer unfriendly moves SU makes aren't always forgotten or forgiven. $160,000 that I'll be paying off for decades and those putzes ring me up an extra $150 to graduate? Can't bake that into the tuition? Eh. Be satisfied with the couple grand I'm laying out for hoops/football season tickets every year, because my charity is going to more worthy recipients.
