"...the P-Vine and I are going to get stuck with the grand daughters whlie srep-ie and d-i-l go off???"

Ahhh... "no". I'm with maeve... "no". Just say "no". I'll tell ya what kinda prick I CAN be when necessary. I'd tell the little boy that if he and the bride intened to leave kids and take off I would call Social Services and have them come to investigate the situation before thay had a chance to get out the door. Seriously, I would not let my ass hang in the breeze on that one. Somethin just don't smell right about ALL of this (and it ain't my ass).
