Wound healing

Noah got a miniscule cut on his knee yesterday, but it bled a tiny bit so I (Josh) put a bandaid on it. Tonight, the bandaid started to fall off, so I pulled it off, saying it was all better now. Noah responded, in all seriousness, "Thank you for healing it, Dad. You're a good doctor." Part of me wanted to tell him that, no, I didn't do anything, that this is part of the natural process of wound healing... but somehow this was still the best thing that happened to me today.
