OK, in our house we often talk about the "packing gene." It's the one that Kim has that enables her to put more dishes in the dishwasher than I can. It usually shows up when I think the dishwasher is full but there are still dishes in the sink. Kim exercises her "packing gene," and more dishes get crammed in, rearranged, etc.
I think there may be a "spelling gene," and that some of our kids skipped out on it. I'm a good speller. English is a tough language and I guess all the phonetic reading that I learned as a kid really came in handy for spelling. I can even spell hard words usually. Not a Scripps level speller, but I'm pretty dang good. Our oldest has always done well with spelling. The next one, not so much. The third was also great. The fourth, he's positive about it, but he's having to work hard at it. Notice a pattern?
So, the other day, the three year old and two year old have this conversation:
Isabel(3): W makes the "wuh-wuh-wuh" sound, like wuh-wuh-water, and wuh-wuh-wet.
Audrey(2): No it doesn't! W makes the buh sound, like "buh-buh-buh" sandals.
Someone missed out on the spelling gene.
