Blonde and the mailbox

An old man was out watering his garden when his blonde neighbor came out. She walked to her mailbow, opened it, closed it and walked back inside. A couple minutes later she came out again opened her mailbox and closed it. She did this a couple of times and each time she seemed to get angrier. Finally the old man watched as she walked to the mailbow looked in it and slammed it shut. The old man asked “Why do you keep checking your mailbox?” the blonde looked at him and replied “My computer keeps saying I got mail!”
