How to hang a mirror (a very large mirror)

So my neighbor, Matt, calls me and says he needs help hanging a mirror. I'm thinking OK, no problemo. As soon as I walk into his apartment I know this isn't going to be good.

The first thing I see when I walk in is two hooks in the wall side-by-side. I just shake my head and ask about weight distribution (this mirror is at least 60 lbs.). Keep in mind that I'm the daughter of an engineer. I know some basic picture hanging etiquette. I'm not saying I know the best way to do it, I'm just saying I know you're not supposed to put two hooks in the wall side-by-side. Matt, of course, sees no problem with this and dismisses my weight distribution comment.

I then ask how much weight each hook can hold. I think this is a logical question. Not according to Matt. The package says "heavy duty" with no weight amount listed. Not a good sign. Yet, Matt is still not concerned.

Now for the big question: Did you at least find a stud? Ha. HaHa. HaHaHa. Studs? Who needs those?

Oh, and did you take any measurements? The mirror is large. Very large. We're going to have to lift it up pretty high to catch the wire on the hooks. Is there enough space between the ceiling and the hooks? Pish posh. No one measures.

Also, he has no tools. I had to bring mine over. I'm pretty sure he "hammered" the hooks in the wall with a soup spoon.

Oh dear god. This has disaster written all over it.

Matt thinks all my points are ridiculous. Thus, he wants to move forward with hanging the mirror. We lift it up and slide it down the wall. It catches something...that something is the frame...not the hanging wire. He makes me continue to do this about eight times. I finally point out that there not enough space between the ceiling and the hooks because we need to lift the mirror about four more inches to catch the wire on the hooks AND THE CEILING JUST HAPPENS TO BE IN THE WAY.

He takes out the hooks and moves them down. I suggest separating them yet again. He ignores me. We lift the mirror up again...and again....and again. The wire is not catching. By this point we're both sweating and I'm laughing uncontrollably about how ridiculous this is. So I look at him and tell him to figure it out while I take the dog out.

I get back in and this is what I find:
1. Roughly 20 holes in the wall. Someone decided it was a good idea to find the studs.
2. The hooks are separated...about 16 inches apart...16 inches is important because that's how far apart studs are, not 12 inches apart, which is what Matt thought...and which is why there's an excessive amount of holes in the wall.
3. Someone was also taking measurements to remedy the height issues we were having.

Hmm. I don't know about you, but those things sound like all the things I mentioned before this fiasco started. And once all of those things are taken into consideration, we lift the mirror up and hook it on the first try.

Need I say more?

I even made him clean the mirror. Poor guy didn't know why he got himself into by inviting me over to help.
