I noticed a few "unwritten rules" posts today and decided to have some fun with it. Actually what got me going was this post ValleyWag on the unpublished rental rates of Wi-Fi in cafes. Interesting new social problem and it could have been the "unwritten rules of Wi-Fi in cafes."
Unwritten rules can be well, enigmatic. I did run across all the unwritten rules below.
What's you favorite or craziest unwritten rule (or is it against the rules to ask)?
