I worked from home yesterday and decided I'd go for a gentle walk up to the local park and back to get a bit of exercise and to keep my feet used to being barefoot. On the way back I was approached by a little boy on his bicycle. He greeted me, which was quite refreshing, and then asked "Why aren't you wearing any shoes?". I replied: "Because I don't want to hurt my feet". A puzzled look appeared on his face, a little pause and then he asked: "How do you ride your bike then? It hurts if I don't wear shoes". He wasn't too interested in my response as he rode off, but his response made me smile.
