How easily some people insult others. I'm not lying. When I have a mystery problem, until I know the reason for it, I try to consider every possible reason for it. Of course there is no way to know if one has considered every possibiltiy
a) How do you know that? b) I never said I did. I said he needs to consider every possibility, and when I have a mystery problem, I try to consider every possibility. That doesn't mean I'll think of every one, but more importantly, even finding the right reason for the problem does not mean someone will solve the problem. I want to take 3 years off and travel around the world. And I don't want to stay in group hostels on this trip. The problem is I don't have the money. Knowing the problem doesn't solve the problem.
No. It was a hypothetical, and I didn't mention myself or my friends. It's the OP who has a problem with the swamp cooler.
I never said that, and I think you must be a sloppy reader to keep saying I said things I haven't said. I said that "he needs to consider every possibility." That doesn't mean he *or I* have thought of every possible reason his swamp cooler is causing problems.
It depends on what it leaks on. It might have an overflow that routes overflows to some harmless location. Or a friend who is playing with him might not realize that it's actually overflowing enough to cause damage. The OP didn't say it was causing damage.
Even if the leak turns out to be nasty, that's not enough to say his friend is nasty. It depends on the friend's intention.
