Someone else than this friend. You will feel awkward/worried about how it will look, he may feel weird.
I would say don't respond. I am not dead set about it after this email but still it would be interesting to see how he reacts. Oh, I would not respond to the last contact lenses email...
About a possible OP: ignore!!
I'll be there in a way. A little voice in your head, it will speak Greek but you'll know what it will be saying...
