Dear Holly,
For this past week, we have stumbled into a new tradition in which you and your brother work on Legos while dinner is being prepared. As your brother labors over complex mechanical creatures, you just work with a handful of pieces.
Typically, it’s 2 or 3 Lego people and only enough pieces to build a small living room.
I’ll hear you do a falsetto mutter, which is apparently them talking to each other.
It is as if you are playing house, with Legos. You can spend an hour playing with just about a dozen blocks- and you’re happy!
Love,
Daddy
