history: I was working on a boat, and I had to hope that my friend didn't screw something up while I had my hands in the engine. Gosh I hate it when I have to work on complicated parts in my boat engine_comma_ when my friend is helping me. Have you tried seeking expert help? Nah I can do it myself_comma_ I just have to hope that my buddy doesn't do anything crazy when my hands are in between the hydraulic lines. 
current: hahahahah so you are more worried about your friend than actually fixing the boat?
next: Yeah I can fix the boat, I just need to be sure my help can handle their tasks appropriately!
