I'll at least speak to Ajab.
Many of you may not have known this, but he dealt with some pretty debilitating chronic pain. It was bad enough that he often had to put a lot of his life on hold because he could barely get out of bed. I have people close to me with some pretty bad issues with chronic pain, but Ajab felt so isolated by his experience with it, and it was impossible not to feel for him.
But every several months or so, he'd give me a call and we'd talk about everything. And I do mean everything - life, family, philosophy, religion, etc., and nothing was out of bounds. I don't get the impression that we agreed on everything, but we could relate to each others' positions. Nothing was combative. It may seem strange for an American Jew talking to a Pakistani Muslim to find so much common ground, but I looked forward to every conversation we had, to every distraction I could give him, and every bit of solace I could provide. Only wish I could've done more.
