MonoMonday:Entrances and Exits

MonoMonday again, they do seem to roll around quickly! Thanks to Paladian for hosting the challenge once again!!

I've taken a lot of different shots of entrances and exits today but this one of my local Post Office Boxes appealed to me the most.

Each little numbered box has an entry inside the post office so that mail can be put into each one and we come and take our mail from this side (exit). So it fits all the criteria, and I picked up the mail at the same time! ;o)
