How long has it been since you've heard from your uncle?When was the last time he wrote you?I can't recall how long it's been.I'm always disappointed when I don't get any mail.I feel guilty because I haven't written her lately.What time is the mail delivered on Saturday?The postman always comes at 2 o'clock.I wrote to my uncle last night. I couldn't put it off any longer.I enclosed some photographs in my letter.I didn't know whether to send the letter airmail or not.
