person A: Gosh I hate it when I have to work on complicated parts in my boat engine_comma_ when my friend is helping me.
person B: Have you tried seeking expert help?
person A: 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. 
person B: hahahahah so you are more worried about your friend than actually fixing the boat?
person A: Yeah I can fix the boat_comma_ I just need to be sure my help can handle their tasks appropriately!
