Yes! Absolutely. The human senses play some amazing tricks on our minds. Even just seeing a person in the corner of your eye can trigger things you don't even realize. Simply put, if you want to be happy, you need to be around cheery, joking, happy people. Also, I don't know if you're into studying personalities much, but they play a HUGE role in this game. There are four main types of personalities, and as others have said, you may have noticed that people have different energy levels and feed off of others. This is all very true. doggiedo is correct, you may not realize it but you also have influenced those very same people in their lives. If you think it is just not working out, it really is best to simply get away from them for a while. I'm available if anyone wants to pm me.
