What if someone you know; very talkative become very quiet?

If someone very talkative turns to be quiet especially if he/she is my friend, I will approach him/her and ask if there is something wrong, if he/she has a problem.

If I know that person too well, I will ask him/her if he/she has a problem or if there's something that I can do for him/her. It is unusual to see a jolly person so quiet so if he becomes like that, there must be something bothering or something is wrong with him...

Hi, People can change from time to time. Sometimes, when I feel down and sad, I can be more quiet than usual. From my personality, I am not a quiet person,so when I act to be quiet,it means something is wrong or something has happened who make me feel sad and need to get myself alone. When I feel happy, my face will full of smiles and I just feel like talking to someone.

i am a talkative person .....and sometimes i also gets upset and keeps quiet....my mood is very unclear......sometimes i get very happy for no reason and sometimes very sad for no reason too....but maximum times i gets upset for a reason....i am quiet because i am not happy with my current life....there is something missing in my life..... you should take that person into confidence and ask him the reason behind the quietness....you should make him feel comfortable with you...so that he will get someone to release his thoughts... happy mylotting

There must be some thing unhappy.If he or she is my friend.I will try to ask him what happened.Whether telling me or not, I just comfort him in a normal way.Such as everything will be all right.But if I know the truth,I can comfort him better.
