Oh JT I am so sorry about your brother.
Maybe I will try tip toeing around mine. He's 5 years younger than me, which is not as far apart in age these days as it was say 15 years ago. But we've always hung out together, even when we were little, and we've always gotten along and rarely fought.
I guess this is one of those risks you have to take in life so you don't end up regretting it later...
