I meant to tell you a story.
Every night on the way home from work I drink a glass of water. I normally have a plastic cup with a straw to make drinking easier. Last night I forgot a straw, so I knew I would have issues (ever drink out of a regular cup without a straw while driving? Not the ones that have lids that you can drink from, but a lidless cup? Try it. Try drinking and braking and driving over potholes and see how you do).
Anyway, so I was very careful about drinking my water – making sure that I only drank when the road was clear, traffic was smooth or I was at a light. At some point I went to take a sip and had to brake suddenly because traffic came to a near-stop. The water flew to the back of my throat and caused me to cough. I had a full mouth of water at the time, so I clamped my lips shut and tried to cough gently. A small spray of water came out. It struck me funny, and I coughed/laughed. More spray – this one a bit bigger.
“Don’t laugh, don’t laugh!” I thought to myself, willing the tickle in the back of my throat to go away. *cough* Biggest spray yet – going all over my windshield.
I was finally able to swallow the water (yeah, didn’t think at the moment to just pick up my cup and spit out the water altogether) but was left with a water-soaked car interior. My coat, my steering wheel, my dashboard and my windshield were all covered and unable to be cleaned. Nice.

Oh, my goodness, that was a great story! Glad nothing too horrible happened! hee-hee. I’m just imagining water spraying all over your windshield, and what it would’ve looked like to someone watching from another car.
I choke on water every couple of months. It’s annoying. Even moreso at work. Fortunately, I only spit my water all over the floor, ONCE. And nobody was there! Whew!
