Yes, I rather think Severus would relieve his loneliness in this way rather than heading out to the bingo and church suppers. When I read fics where he is in his dotage, it amazes me how many have him mellow and sort of excentric but cute. Snape, ladies? No. My Severus is snarky and insular right up until he turns up his toes.
Thanks for the comment and apologies for the hankie usage.
