Had a few on my hands and feet growing up. One on my big toe when I was about 15 the doctor froze off.
I'll say this: you can freeze them off yourself if they're not too big. Get a can of that shit you spray on electronics, that dust off stuff for keyboards, etc. Turn the can upside down and spray it on a cuetip, the touch the cuetip to whatever you need to freeze. Do it a few times, to get deep. Don't spray directly, as it is haphazard and you'll freeze healthy skin. I got rid of a pretty bad case of molluscum on my daughter this way. If you have to do it on your kid, do it in the middle of the night when they're conked out. It hurts when awake.
TS-- that sucks man. It's good that you're so responsible and conscientious about it. I've know "adults" with STDs that still fucked everything in sight with impunity.
I agree with you on having shoe/show free zones. After living for some years in Japan, westerners seem just plain barbaric in wearing that same shoes ini front of a public urinal, taking the trash out to a dumpster, and right there are the foot of the bed. Just gross and really ignorant, I think. We don't weear shoes in my house, and my mom still rolls her eyes, as if it's just meant to be an inconvenience to her, and that somehow her shoes are clean. My kids run around and play on the floor. I don't want someone walking from a shit filled dog park to my living room rug then rolling their eyes when I ask them to take their shoes off at the door.
I'd bet dollars to doughnuts that people have lower rates of plantar warts in Japan. We have a lot more cold sores in the states then in most places, too.
