Thanks, yeah he has gone somewhere quite touristy (much to my dismay, given the covid situation- though he promised he would stay out of the way of people). I didn't think about post delay possibility. I assumed he meant he would send me something before he went but we didn't actually specify, so maybe? That would mean taking my address on holiday with him which seems a bit of a faff.
I wish he had been more specific about what he planned to do.
