It does happen though. Nothing/nobody is perfect- not even the mail system.
A few years ago, my aunt sent me a birthday card. I never recieved it.
Also, a couple years ago, my mom sent me something. She was mad that I didn't get it but after like a month, we forgot about it. Well, over a year later (Yes, 12 months!) I recieved it in the mail.
Crazy things do happen.
