I’ve just received a FB ‘friend’ request from a Canadian cousin. I had never met him before he invited himself to stay over 10 years ago. He stayed 10 days, was taken all over London to see the sights, and barely ever put his hand in his pocket, even while on a requested a pub crawl with adult dd (a good 20 years his junior) - she eventually had to tell him ‘Your round this time!’
After he left, there was not so much as an email to say thanks, and there hasn’t been a word ever since.
Nasty cynic that I am, I suspect he’s angling after another freebie stay. TBH I don’t really use FB anyway, except for a closed craft group, but needless to say, I won’t be ‘friending’ him!
