I didn't always have the thick skin I have today.

I developed it.

A while back, my brother told me: "I used to put equal effort into every friendship. I don't any more." He's 22. He's way ahead of where I was at that age.

Some friends stayed. Some friends left. Some friends broke my heart and if I found them behind the wheel of a truck I was driving, I'd probably put it in gear and just go.
