Please refer to the bolded above for context as to my comments:
(1) Not everyone who is happy, or smiles for the matter is fake. Some people are genuinely happy, like me, and we don't try to be that way, we just are, and we're OK with it, and there's nothing wrong with that.
(2) OK, you are getting lost in your own metaphors. How can you dig down deep into someone to find something you can really appreciate in them if you don't ever give them a chance in the first place, because you dislike them at first sound, or first sight?
(3) I think the only thing wrong with you is your attitude and/or that you are hyper-critical of people you don't even know because of pet peeves or stereotypes that you don't identify with. Why do you like or dislike someone based on thier conversation with another, when you have no idea who they are, what they are talking about 100%, or what either of them has been through that day or the rest of their lives for the matter?
You might want to chill out a little bit and maybe for starters, pick an activity that you wish to engage in that you have not already. Then join a club or social group that does it. It is at a place like that, that you have a chance to hear people talk about something that they are in to, just like you. WOW! Maybe then they won't seem so superficial and smiley and shiny and fake?
Not trying to rant, but I think you are taking life and your simple everyday interactions/observations of people WAY too seriously. Try to lighten up a little bit. Smile! It's OK!
