I put my walls up....Who will tear them down?

So, one of my good friends always sends me QOD(Quotes of the day). I get one probably like 4 times a week. I enjoy getting them and look forward to it everyday. I like all of them, but one really stuck out to me the other day that she sent me because it relates to me. It read "Sometimes people put up walls, not to keep people away, but to see who cares enough to tear those walls down". My initial reaction was like that is so deep then about 30 seconds later I said to myself " Wow, I do that to so many people". I talked about in a previous post about I like to only stay in my comfort zone and that's it, and I think that is a lot of why I put WALLS UP and don't like to let a lot of people in which plenty of outsiders have confronted me about in the past. In the end when it comes down to it I'm not trying to shut myself from the world or keep from letting people to get to know me, it's more like when I put those walls up who cares enough to tear down those walls as the quote says. There are a lot of people that have torn down those walls when I put them up, and basically all those people are my BEST FRIENDS!!! So, thanks to all of you for loving me so much when I put those walls up you tore those down. It means a lot and that's the difference between our friendship and others I may have.
