Input: Text: tifu.. as i drove home today i noticed in my rearview mirror a very beautiful porsche that was rapidly approaching myself and the swarm of traffic that surrounded me. like most people that drive expensive cars, this person was driving like a complete asshole, weaving in and out of traffic like someone was about to give birth in the backseat. also like most expensive car drivers, they ended up sitting at the same traffic light as the people they so earnestly attempted to get around. as i was running on about 4 hours sleep and a very limited supply of patience i decided to give this horrible driver a piece of my mind (and a certain finger) as i pulled up next to them at the light. i rolled down my window and gave the best military-grade "hey!" shout as i could muster, finger at the ready. the tinted window of the porsche slowly rolled down to reveal the weather beaten face of what appeared to be a 80+ year old woman, complete with a handicapped tag hanging from her mirror. my jaw dropped at the shock of realizing the 90mph-in-a-35mph-zone-driver was old enough to be somebody's great-grandmother. she yelled back at me in a wonderful mother-goose tone of voice "am i goin' too fast for you sonny?" then put her car into gear and sped away at the limits of her car's engine... and that's how i got punked by an old lady today. long live the fast lane, mother goose!
