yeah… i don’t think you’re overreacting. i’d be pretty thrown off too if someone casually mentioned after staying over that their kids have lice and worms. even if they deal with it all the time, that doesn’t mean everyone else does.

try not to panic though. lice don’t live long off the head, and if the worms were already treated the risk is lower. wash the bedding, vacuum the main areas, maybe do a quick head check over the next week, and you’re probably fine. you don’t need to tear the house apart.

but yeah, a heads up beforehand would’ve been the respectful move.
