I've never heard such a rule about the college thing.
Blondie, your're right about that last ref. to the WT article on celebrating one's newly baptismal. But I did get a card from a sister in my hall. (She was a regular pioneer who was deathly afraid of getting pregnant and was religiously on the pill-but I saw her 2 months ago and she's got a daughter now, blew up like a whale and is struggling as a cashier at Home Depot; How sad.)
Anyways-yeah, after my baptismal my folks did not take me out to dinner, no gifts, just a hug and a reminder that "now if I messed up I would have to ansewr to Jehovah" Gee, Mom-that advice has really lit up my day.
