They should get napkins.

Olly, Perhaps it equates to instinct 🤔

G Brown, 🎼perhaps she'll die🎼

nele, I was told by a pest control employee that they were as successful in killing flies and roaches as they were because if one of them goes through something – like bugkilling powder – that makes them feel "dirty," they will stop and clean it off.

I knew an old lady who swallowed a fly.

fly with cleanliness what a contrast

Olly, instinct
