You shouldn't rummage through other's belongings.
Han was over at his friend Luke's house waiting for Luke to finish using the restroom.
Han wants to do something while waiting for Luke.
Han looks at the posters on the wall that Luke has up.
Han looks through Luke's things and finds a wad of $1000 bills.
Han is curious where he got some of these cool posters.
Han is freaked out and wonders in his head the rest of the time where it came from.
