I don't understand the 'gifts'. Are they nothing more than a way to send someone a pic and message? I received 10000 gift, but as far as I can tell all I can do with it is stare at it in the garage or delete it. Is it really nothing more than "Hey, I just blew xxx crystals to send you this message...enjoy!", and only difference between 250/1000/5000/10000 is a stupid picture?
