How are your new sharks doing?????????? I LOVE that you bought sharks. Did your children talk with H about the fish tank or the new sharks? Maybe you could do something special with the fish tank (e.g. buy special food; take videos of the fish swimming around; add some funny toys to the tank; name the fish and make up funny little stories about them, referring to the fish by name; have a birthday party for the fish at dinner one night, wearing party hats) so that when your kids spend time at H's, they will talk about how much fun you've been having with the fish tank...........Just throwing ideas out there.
My TT games with XH, which have become one of my primary connections with XH, began when he asked me to buy something from a store that he doesn't have a membership to (I got that membership in our settlement). I told him that I would do that for him if he would barter services with me. One of the things I asked him to barter with me was practicing TT with me one day......That was last June and now we're playing weekly and going out to restaurants afterward.
Great idea to submit change of address card for H's mail. Let H deal with his junk mail for a change!
Will H be contacting you more to exchange info for taxes? That could be an opportunity to DB too.
