Sometimes I mail my kids random letters

I don’t just put them in the mailbox at the front door. I sent them through the post to be delivered by the mailman . Sometimes the letters are just meant to brighten their day or give them something to look forward to in the mail. Other times, I'll send a letter if I sense they're going through a tough time or dealing with a sensitive issue they might not feel comfortable talking about. I’ve done this since they were little. They still love receiving the letters
