Is a helping hand always good?

Hannah Montana said it before: nobody is perfect. Good intentions do not always result in good actions. Sometimes things get a little more complicated before they start to get resolved. 

That's what happened between these friends. A broken car and a seemingly low budget. One asks the other to help fix the car's belt. The problem is, nobody really knows what they're doing here. The second friend, in an attempt to be helpful, tries to work on the broken car. However, misinformation and inexperience result in a fatal mistake. For you mechanics out there, you know how problematic it is to add lubricant to the belt. For those of us who don't know a thing about cars, just know that it is bad, no doubt. 

A small problem started growing, so they had to involve an actual mechanic. As predicted, the belt now has to be replaced. Here's the controversy: friend number one is asking friend number two to pitch in with a third of the money needed for the repair, arguing that their good faith intervention resulted in the escalation of the problem itself.
