IB, It would have irked the heck out of me too. Sometimes the "in the face" crap will get to you and I'm not just talking about the two smoochies. You will, at some point in time, sit back and laugh about how stupid they looked in public.
Wishing you and your family a very safe, blessed and happy holiday season. May the new year bring many surprises and good will to you and your family.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
