Thanks for all of your thoughts and opinions, everyone. I have been sick with an upper respiratory infection (and continuing to work half-days with it) and have just now made my way back to read.
Indeed, I have acknowledged that I've handled things badly in many ways..I'm nothing if not honest about my failings - and there are many to choose from.
This is why I came to you fine folks for advice in putting emotion aside and focusing on the etiquette of the situation and, as always, you all stepped up.
Here's where we are:
My parents are taking everything except the kayak as my dad has come over and inspected what is here and is agreeable to it. My parents like him well enough and are willing to do this in order to help both of us move on. The items aren't going to take up much room in my dad's SUV, but I wanted him to inspect them to be sure it wasn't an imposition. I also spoke to my son and his gf, as they live with her mother and wanted to be sure that it was okay with them (and mom) to store this large tub of items in their garage, etc. There is a shop-vac, some tools, etc in addition to the tub, but they will fit nicely into dad's SUV.
I want to send him an email instructing him that the items will be arriving via my parents and give him the date, and that they will be handed off to my son and his gf. I will advise that I understand that they haven't yet met up for the computer part, and that hopefully they can set a date soon to get all of the items handed over together. Note; I will not say that sentence in a judgy tone at all. TBH, I don't know if it's my son being flaky or him. According to gf, it's him - and she has always been the type of person that would readily admit if my son had dropped the ball. We have a great relationship
..but I digress.
Further, I will advise him that the kayak can remain until (whatever) date, and to let me know (via return email) as to when he will come get it, or who he is sending for it and when. I plan to send this email from a rarely used one that I keep mainly for when I sign up online for something and feel they may spam my email address.
Do you think I should touch upon the fact that I don't plan on selling the kayak for him, just to get it out of the way? I suspect that he'll reply and try to push/argue the point. I want this email to be as coolly polite as possible without crossing into rude. I don't want to invite a bunch of back-and-forth between the two of us.
What do you all think?
