Thanks everyone.
It was sort of a serious event amongst friends, because some prizes and points etc were at stake
Under wet conditions these days (this part of world), people seem to pick up their balls as they please, which makes me ask myself why did he do that????
In this particular case, I wasn't thinking his ball might "assist" my play. This is perfectly valid point considering his ball was indeed directly on the line of my next shot, and I could have used it to align myself. I never thought that
But he could have told me and others what he was going to do and why.
Depending on what he says, the action might have been different. e.g he could have made his shot first.
Anyway, it is nice to know what the rule says.
Thanks again
