We don't write on the back, but I often see other country's people write also on the back . It's really interesting:D
Usually I write on the back. I suppose it's a question of using all the paper (and, if you send a long letter just written on one side, it would be expensive). do you mind if I write on the back?
you're right, writing also on the back will less cost postage.it's just culture difference, I guess:) and I don't mind at all if you write on the back:D
Thank you for coming. All your comments make me extremely happy.
