Alan is the kind of person that you can trust your life with, blindfolds on. Everyone at least needs one Alan in his or her life, someone who you know will always be there when you need support and help, someone you can trust more than you trust yourself. I would jump off a plane if he is in charge of the parachute.
Alan is the ear to your inner voices, a sounding board to reflect on yourself and come to your senses. He is the reality check when you are gone off track and the conscience signaling on the background, guiding you back to safe shores. When confused, just ask yourself, "what would Alan do?" And you'll know what the right thing to do is.
You can trust him with your darkest deepest ugliest secrets and you can bet with your life that he will never even hint to knowing anything about it to a soul. There will come a day where even you would forget that you ever told him about them.
Alan takes care of everyone around him. If you are ever blessed to be on his radar, you are insured for life. He would be helping you without you even knowing it. Even when you think he is far, you can be sure that in one way or another, he is making your life better in one of his own magical discrete ways.
I can talk about Alan for days in a row but no matter what I say, I wouldn't even be close to describing what he is for me. All I can say is I must have done something good in life to deserve a big brother such as Alan and I pray that I'd never have to go a day without having him present a phone call or a message away.
