how much Lego we own?
Roger wanted to be sure our future children had plenty, so we started investing in it when we got married. Christmas presents. Birthday presents. We collected it for nine years before Jack was born. Then after he was born we kept collecting it. Christmas presents. Birthday presents. (And, okay, bribes for good behavior.)
I don't think we've stopped yet. Jack gets a monthly catalog from Lego. Roger gets regular email updates from lego.com. Not ten minutes ago he showed me the one offering free shipping on the awesome new camper van set.
One time I made the mistake of asking whether we had enough Lego. Apparently it is impossible to have enough Lego.
