There's definitely a tendency to OCD that runs in my family. I won't bore you with too many details. Suffice it to say that it has manifested in the new generation.
Sofi, at age two, had to clean off each step up to the slide before stepping on it, all the while muttering under her breath "dirrrrty, dirrrty!".
Judah, at nineteen months, finds it neccessary to pick all the fuzzballs off my sweater, all the while muttering under his breath, "Yuuucky, yuuucky!"
Just doing my part to pass on the family crazy.
