Let's Do The Wave.....Or Not

Either I'm getting more and more fed up with inconsiderate people as I get older, or some people are just plain rude.  When you are sitting in traffic, waiting to pull into the lane that I am in, and I wave for you to go ahead and go in front of me, please feel free to show a little appreciation by doing "the wave".  I don't ask for much, just some acknowledgment of my kindness to you....a stranger.  I can honestly say that I ALWAYS give a little wave to the person that saved me from gathering cobwebs as I wait for the seemingly endless stream of cars to pass before I can pull out onto the road.  I admit, I can sometimes be a bit discriminatory with who I let cut in.  For example, if you are elderly- you're in; a teenager- depends if you look like a punk, if so, then no; a woman in a Lexus talking on her cell phone- OH HELL NO (and don't flip me off because you think I owe you, I don't owe you nothin'); any other random person- you're usually good to go.  And if you remember to wave, I am impressed.....and am tempted to write down your plate # so if I see you again you're in! :)  For those of you "non-wavers" it doesn't really take up much of your precious time to give a little salute.....you would have spent more time had I not let you cut in.....and maybe next time I won't let you in at all!....and perhaps I shall give a little one-finger wave to YOU instead.
