Went out as a single and joined a 3some. One was a non-stop talker. On #1 tee. I was 4th to hit, and he was still talking. I backed away twice, and he finally realized why "oh sorry dude, I'll shut up".
He didn't. Never stopped talking. I'd rush to the tee box to hit before he got close. I still got in an amazing groove, through 13 holes, I had hit every FW, and only missed two greens (both on line, one back fringe, one front fringe) and sat a -3 going into an easy #14. Yet the talker launched again right on my downswing, and my drive sailed right into the trees. Immediate apology. And then I had to listen to him apologizing about how he ruined my perfect round for the last 5 holes. I think he was happy to have something to keep his mouth moving, maybe he was running out of things to say. He apologized at least 40 times in the last 5 holes. And couple times more in the parking lot.
I bogeyed 14 and 16, but rolled in a long birdie on 17 to stop the bleeding. I will make sure I am not paired with that guy again.
