The Weed Connection has a funny page about Smoking Etiquette...Here's the first one about a problem we all have with people Stealing Lighters....
Stealing Lighters....Everybody has stolen a lighter or two before. You probably have half a dozen lighters sitting in your drawer right now!. Stealing lighters is a bad habit and can really leave your friends pissed off. In the case you do steal a lighter it's cool as long as you follow these few simple rules:
1) If the person asks you for it and you have it..give it back!
2) If it's a cool or expensive lighter...dont take it!
3) If you realize you stole the lighter by accident...give it back!
Check out the rest of them over at Weed Connection.
