When I was in the youth choir many, many years ago, we were handed a new piece to sing and under the title was the subtitle "A Finnish Hymn"
You laugh, but we got a letter last week that was hand written but we didn't know the sender. Opened it up and it was a random letter from Jehovah Witness offering to talk to us over the phone.Heads Up !
If you get an email with the subject "knock knock", don't open it.
It's a Jehovah Witness working from home.
