Handle
Where do you put your fingers when you're on an escalator? On the handle! Okay, so maybe it's not a handle and more of a railing, but for the sake of this kanji, picture a handle instead.
きゅう
あつか
None
You put your hand on the handle and an old person leans in close to you and says, "暑か?" (あつか). He wants to know if the handle is ... hot? Before you can respond he says it again, and again! “暑か？！ 暑か？！？！ 暑か？！？！？！” he's shouting as you slowly ride the escalator away from him.
