Act of deviance

This week, for my act of deviance i opened the door and held it open for everyone in my economics class. You would think that people would say thank you, or at least smile, right? but that wasnt everyones reaction.. as a matter of fact that was NOBODYS reaction besides one person. People walked in and did their best to not make eye contact.. whether its because it was awkward for them or not, it was just plain rude. Many even gave me a weird look, one asked why i was doing this. When i responded by saying "i just wanted to do something nice for someone today" (not wanting to explain how this was an assigment, blah blah) he gave me an even weirder look and said "whatever" as he proceeded walking. It was interesting for me to find out that such a nice act did not even get one thank you out of at least 20 people that walked through that door, and i sure wasnt going to do it again. I kind of realize why people really don't do anything nice for anyone anymore. Because of the way society is, people do not expect for someone else to do something nice for them anymore, and if they do it's because they need something in return or there must always be a reason for their act of kindness- there is no more "just because :)" If more people engaged in a positive act of deviance everyday, holding the door open would not create so many shocked faces and weird reactions.. someone did something nice for you, say thank you and smile.
