Now wait a minute, KV. You are taking the guilt too far. I kind of want to shake you a little and say "get a grip on yourself". This situation is NOT irreversible. This too shall pass. A year from now you'd likely be able to look back on it and shrug. It feels like it's looming larger than life, and from an outsider's perspective, I don't think it's really all that bad. I also do this sometimes -- blow my self-perception of a behavior way out of proportion and feel like it's the end of the world, only to later learn that the other people involved just didn't think it was nearly as big of a deal as I obviously did.

I understand that your son and his in-laws are upset, but I think it's VERY likely that the accusations you are feeling are disproportionate to the reality.

My house is less than five miles from yours, and I'm not seeing 'wet, cold, grey, dismal'... I'm seeing 'a cozy day to stay inside'.

You need to eat and warm up. Want me to have a pizza delivered to your house? ;-)
