Scratch it and sniff

Q:  Why do people feel the need to put the flowers they got for Valentine's Day up on facebook for all the world (or their 65-674 friends) to see? 

A: People feel the need to constantly show how amazing their girlfriends or boyfriends are so they can get reassurance from the world that they are in a good relationship. 

Q:  Don't you think that maybe these people just want to show how pretty the flowers are to everyone and there is no other agenda?

A:  No.  There is always another agenda when people post the flowers they got.  Yes, I'm sure the flowers are very pretty and it was a very sweet gesture but there is a bit of need for attention when the flowers are posted. 

Q:  Why do people usually follow the flower picture with a quote that says something like, "isn't my so and so awesome?"

A:  Again, these people want to be validated that they are in a good relationship.  You don't see them post pictures of an empty table with no flowers do you?  No.  They only post when the significant other does something sweet.
