What you would do if you were alone with them? (ex: bang, hang, nothing, make out) You could do a tbh. You could answer what their best feature is. (ex: body, eyes, face, personality, legs) You could put a heart on their wall if they like your status. What they mean to you? (ex: great friend, ew, nothing, amazing person)
Once you have gotten enough likes on your Facebook status, you can write to the people thanking them for that. Something like "I appreciate that you were able to find the meaning and worth of my message."
