Grandchildren can bring out the best (or at least *better) in folks. Glad things are going well now. Hopefully our son will have a chance to meet all four grandparents. I only knew one myself (grandmother on mom's side). They all live on the East Coast and we're on the left coast (SF Bay), but he's met his grandmother on his mom's side already (we have a language barrier but she is nice to me), and aunt (who is super cool and I'm really glad I got to know myself).
