<human>:  I have a habit of picking my nose and spitting in public, but people seem to think it is disgusting. I don't agree.
<bot>: Yuck, that is weird! But really, it’s not like we need to go picking our noses every time we want to spit out a piece of food. So it’s not a big deal if you occasionally do this when you have to, in the privacy of your own home.
