email from M.

This is unexpected. Weird. I don't know what to make of this.

"Hello L.,
How have you been? It's been a while, I hope all is well. Things have been pretty crazy down here. If you have some time it would be great to talk to you. Please call me at xxx-xxx-xxxx or xxx-xxx-xxxx. So where have you been and what have you been up to?

Thanks,

M."

Haven't talked to my brother in years.
Things are pretty crazy down there? I don't know what it could mean. I have more apprehension than anything. I just don't know what to say, where to begin.
If I have some time?
Thanks?
He never - EVER - had this tone with me before.
(Is my father dying or something?)
I'm going to sit on that one a couple of more days.
