Laugh, uncontrollable
When-ever someone says something the slightest thing humourous...i cannot help but laugh and i cant stop for about 20 minutes. Even when i remember something that happened in the past, i cant stop laughing. Everything seems to funny to me. Once when my friend told me her and her boyfriend broke up, i laughed..there is nothing funny about that at all! Do you think this is normal? And does anyone else do this too? :/
