one day you meet your male friend named Ryan in the park. You approach him and start a conversation and small talk then you ask his favorite hobby, then Ryan answers in a deep voice

"stalking.."

at first you think it's a cool hobby, then you tell him your hobby

"my hobby is dancing and singing"

you say, in a deep voice and followed by a thin grin Ryan answers

"i know."

at that time your face looks surprised and a little scared
