Sorry your feeling down WHG. D talk can definitely do that. I still get an instant pit in my stomach when my w mentions it.
Will your W allow you to take SD & SS out for dinner or somewhere w/ your S? Have you asked and would you hesitate to ask? Letters/Postcards are a great idea. Maybe if you see something they are interested in snap a picture and include it.
Do they use email or have cell phone u can text or have you agreed not to do these things?
I feel you about the love/family items. I think they may have always been there but now they have such a different meaning and we are more aware.
