My little friend was six months old. I didn't even know I had the little friend until my cousin-in-law Patti told me it wasn't a callous but a wart while in Carolina for New Year's.It was already 4 months old by then. The standard Western treatments weren't gonna discourage it, though I tried them. Julia tried the traditional Indo home remedy a couple of times, but it just hurt a lot. If in the US, I would have been able to walk into a dermatologist's and frozen the bugger and watch it fall off in a week, but I delayed consulting a physician in Indo, because that's not what happens here.
