ECN Forum Forums General Topics of the Trade General Discussion Area 13 Things ....

I just saw some lists of '13 things XXXX won't tell you." For example, here's one: http://www.rd.com/advice-and-know-how/13-things-your-pizza-guy-wont-tell-you/article122354.html

How about such lists for us? Say, "13 things your contractor won't tell you?" What would you put on such a list?
