Somebody once told me that they thought I was materialistic but after knowing me for a while realised that I wasn't -- I was merely overly fond of my things "because things had never hurt me, like people had."
I think that is the truest statement I have ever heard in relation to me.
When people say I am hard to understand, I've always felt I was very easy to understand -- I am reactionary.
If I am treated well, I respond favorably but if I am treated poorly the defenses go up and I keep my distance. In some cases, I've been known to simply disappear from someone's life. This isn't to hurt them as it is to protect myself emotionally.
