If given the choice I would show up to work everyday without socks or shoes. They are the first thing I take off when I get home. Sometimes I don't even wait till home and I take them off once I get in the car. Shoes are something I wear only when required- like mowing the lawn and going into stores, work, restaurants. The rest of the time.... I'm barefoot.
So my son's new shoe obsession is nothing I can claim responsibility for. Doesn't matter whose shoes he finds, he immediately goes to put them on his feet.
I guess the plus side of this is that I'll never have to fight him to wear shoes in the morning for school, church or something.
