Always wrong

I have to say I am not sure what is wrong with the delivery men in our area, but for some strange reason I get something delivered to me once a week that is not mine. They always use the same line when I am chasing them down the street. They tell me that they looked at the street and it was the same as mine. I have the same house number as the street I live on. It seems like they do not really pay attention. If I was not an honest person they would be loosing a lot of packages because they are giving them to the wrong house. I was thinking about getting a home address signs that spell the street name rather than have the number. I wonder if that would have an impact on them reading the numbers right. It sure would be nice to get my packages once in a while.
