Our mail is delivered through a slot in the front door. It usually scares the heck out of me when the mail is delivered because it sounds like someone is trying to get into the house.
On the other hand, when one needs to mail something, the only option is to find a post box. From what I understand, our postman will not take any outgoing mail, even if you hand it to him. The red Royal Mail post boxes are all over the city, and we happen to have one just a block away.
It is not the most adrenaline-filled trip when we take a field trip to the post box. However, Youngest Kiddo is always happy to go with me. Mostly because of the zebra (zeb-rah) crossing.
The quick constitutional helps him burn off some energy.
