The more important some communication is, the worse I am at writing. Or I'll start something, but want to include everything, not have time and then it gets old. Some of my closest friends are ones that I have done very poorly at keeping in touch with, not because I don't think of them, but because I really, really want to do a good job of writing them. Sometimes I solve it just by phoning and catching up, then it makes the writing a manageable amount, particularly if there's something between us to be addressed. If you're not on phoning terms, that option isn't open to him. It may be a compliment, more than a comment on how unimportant you are.
