So frustrated I could cry

And no, oddly enough, its not TTC related.
We had to replace the shut-off valves under the sink, because they were too small for the lines from the faucet. Kinda bizarre, I thought that shit was standard, but no. So, we cannot finish the bathroom until that is done.
We had to turn off the main water line, and remove the old valves. Now, the new valves won't install properly. I don't get compression ring connections, I don't get how they work, so I can't help Rich. And he is getting frustrated as hell too, and no surprise there. He has been to the Depot about 4 times today. He's been trying to hook this up for ever.
I just want the goddamn thing done so we can put our house back in order. Its KILLING me.
If I ever write about wanting to do major renos again, please remind me how much misery this bathroom reno has gotten me.
F*ck.
