don’t make cups out of styrofoam if it’s not considered socially acceptable to absentmindedly tear them to pieces with your teeth and fingers
actually, don’t make cups out of styrofoam at all
I’m sorry, are you telling me I’m not supposed to gnaw on the edge of my styrofoam cup?
the edge? bruh, you’re SUPPOSED to obliterate the cup and tear it to ribbons with your gnashing maw until people eye you nervously and ask, “so, you’re a fidgeter, eh?”
