<human>: Give me a shortened version of the text

He was hired to do a duct work job and in turn he hired me as a helper. He knew what he was doing and I knew very little. I was simply there to run tools and hold ducts in place while he secured them, etc. He was the real brain behind the job. Well, he decided the half ass the last part of the job by not properly connecting the last couple of ducts that ran directly to the AC unit. I wasnt aware that the job wasnt properly done because I didnt really know what was going on anyway, and I couldnt see the last couple of ducts, as I was on the opposite side of the house already crawling out as he was working on them. Well, 2 days ago, I get a call from his boss explaining what was up and how he had picture proof of all the unconnected ducts and blah blah and the man who wanted the job done is going to sue my friend and his boss if we dont go back and properly secure them. I want to go out there and do it, my friend doesnt want to mess with it. So if my friend doesnt go out there, they get sued and I have to testify since im a witness. If he would just go out there and do it, everything will be fine. But he wont, and I really dont want to testify against him. But at the same time, he dragged me into alot of bullshit because of his fuck up and he wont even bother to fix it. so hes screwing me over too. What do I do? do I testify against him? do i go up there alone and try my best to fix whatever is wrong? what do I do? Im 16, and uncertified in this line of work, it was all under the table.
<bot>: Friend botched a job, wont bother to fix it, so hes getting me dragged into a lawsuit that I dont deserve to be in that can easily be avoided if we just went and fixed it. not sure what to do.
