good bye /good night

当你聊完天的时候，是说good bye 还是 good night? I do not like to say good bye because that will make me a little down. It will give me a sign that i will never heard from that guy for a long time.So i would like to say "good night" or Good day instead of " good bye". Some times , some people say "thank you" to me will give me a clue that like " thank you " but i want to keep distance with you. Maybe they are right, i am too sensative some time. Outside it is sunny. it is time to take a walk and do a shop. Good night, my friends.
