My sis is a horrible driver. She even admitted it to us yesterday*.
A year or two back, my other sis got car sick due to my sis' driving and threw-up in the back seat of her car… Of course, it didn't help that my sis who threw up had quite a few to drink, but that's besides the point. Fast-forward to this weekend, when my sis was part of the 'support-team' for her friend, Myrna, in the San Diego Rock 'n Roll marathon. Well, day before the marathon, Myrna had eaten some bad fish tacos and was feeling a bit queasy. She decided to sit in the back seat (sound familiar now?) and well, vomitted; fortunately for my sis, she stuck her head out of the window to do her business. Poor Myrna.
So a word of caution: if you're riding in the same vehicle that my sis is driving, make sure your seats are in the upright position, tray tables stowed away, and have your vomit-bag ready.
*Sorry, sis, but I had to share it with the people of the intarweb. <3!
