A man's level of "toughness" (as assessed by other men), will determine whether or not his girlfriend will get hit on by other guys right in front of him in public places. If you're deemed a "p*#%y" by other guys and they want your girlfriend, even in your company she'll be considered "fair game".

I believe most people are good, even deep down, even if you have to dig a little - although some people can tempt one to pick up a shovel and actually put that to the test.
