These are exactly the things I was going to say to do. Anything and everything you can do with the kids and SO. All those things you said you'd play with them in a minute and forgot to get around to. Find some new stuff to explore with them.
So sayeth the part time dad who told his own 'ok, in a minute' and got distracted so we couldn't play the game the last night I got to see him before he headed to Cub Scout camp without me cuz work won't let me. (learnin the important stuff the hard way)
