I play regularly with 2 60-year old brother-in-laws and a 36-year old friend. We paired up, as usual .. me and one of the bro-in-laws against the other 2. for some VERY small stakes doubles skins. Now my partner has this terrible habit of standing right behind me, in my line, when I hit...even on the green. I've been playing with him for 4 years and have politely asked him to move numerous time. I've been getting less polite about it lately. He plays nearly every day, has been playing for years and should really know better. He did it to me on the tee twice yesterday and I told him not to do it again. Oh and he has a tendency to move around back there also. Late on the back I had a 7-footer for par to take the hole. He had a 6 footer a couple of feet over so he stands directly behind my line ... no more that 4 feet. I told him to move and he said "can't I watch the line ?". Well I sort of lost it. Instead of telling him to move back about 15 ft and watch the line, I read him the riot act , (FWIW, I'd been sinking a lot of putts and he'd been killing us on the greens all day) telling him that this wasn't just some strange quirk of mine but basic golfing etiquette, like keeping your mouth shut when someone is hitting. I apologized for getting hot the next hole and he said he was sorry... he just forgets and he knows another guy like me who that bothers I think the general consensus was that I was a bit of a about it. I didn't cuss him or anything but I did make my point rather strongly. Any thoughts or similar experiences ?
