how i know this is...
i have now become a horn blower.
i'm trying not to develop road rage or drive like my sister. but big trucks are about to get on my last nerve.
i have had 3 of them in the past 3 days get over in my lane when i am even with them. luckily there wasn't anyone in the lane beside me, but i did give them a good long f-you horn honk.
