Bradley snuggles up to me in bed as we're getting ready to go to sleep. In the process, he grabs my forearm, which is currently covered in eczema.
Heather: Ouch, don't. Your hand is too hot, it burns my eczema.
Bradley: ...what if you were bit by a radioactive snail and so the salt from my sweat is what's burning your skin?
Cue a long discussion about the drawbacks Snail Girl would experience, like having to basically eat antiperspirant so she wouldn't sweat, and dealing with a hostage situation on the Great Salt Lake. Worst power ever.
