I'll put the kettle on and we'll have a chat.
If they lie slap them and say "don't lie to me!!!" :P jk ask "what's up" or "you seem kind of down. do you want to talk about it?"
you got a face like a cats a ss. whats up?
"I feel like you may be upset, what can we do to change that?"
Maybe "how are you feeling" or "what's on your mind?" That way, you get more than a yes or no answer.
Putting a ******* smile on your miserable face....(is that ok?)
"What are you feeling right now?" seems to get more responce than "are you okay?"...the change of communication catches them offguard and they cant blankly get away with the automated "im fine", response that everyone seems to give.
