Witnesses....Or Just Van Drivers?

Did anyone—driving a van—just knock on my door? I didn't answer b/c 2 weeks ago I was hounded by Jehovah's witnesses......and I'm scared they're back for more.

So let's get this straight right now:

If I know you, and you come to my house.......BE SURE to use the BACK door. That way, I'll know I know you. Now, whether you knock or not is up to you. If you at least do the 'knock then enter' that's fine....in case I'm on the toilet and forgot to lock the back door (I don't close my bathroom door, btw). But usually the rule is if the back door is unlocked....it's safe to come in. If I'm doing something I don't want you to see....I'll lock it.

Bottom line......use the back door to my house so I won't think you are Jehovah's Witnesses.

Or, if you are DHL......say "DHL!" If you are another delivery service.....please use the appropriate moniker. Thank you.
