Unicorn - you sound like a great level headed guy. His personality is a bit extreme. I don't think I've ever heard of someone flying across the globe just to accrue miles with an airline or flying to Belgium to purchase chocolates! I can understand why you drifted apart. But as we get older especially, it's nice to have a friend to do and share things with. I would take it for what it's worth, enjoy some meet ups together without any expectations. You've reconnected with an old friend and maybe for a good reason. I think you were very kind to have treated him to dinner and sharing that nice bottle of wine. CHEERS!
