Where's all your help?

I was working last night when I looked out of my trailer and saw an old white guy standing on the dock looking in my direction.  I did not recognize him, but that was no surprise.  The management carousel spins so fast here that I do not even bother to learn their names until they have been around for at least six months.  When I rolled my empty equipment off of the trailer and started pushing a full container into the trailer, the guy says to me, "Where's all your help?"  Now when I have lots of work to do, I do not want to be interrupted to talk to people that I know, much less complete strangers.  I replied, "I don't have any help."  I do not know if he heard the reply because I did not stop what I was doing or even look in his direction while responding.

He was likely just making a joke because there was a large amount of mail there on the dock waiting for me.  But it reminded me how much it offends me when people suggest that I need help.  I know that I can not do everything, mostly because I do not have the specialized knowledge and training necessary to complete some tasks.  But I can do anything that can be accomplished through strength and willpower.  I some times wonder why I refuse to even consider getting help even though it would save me much work.  I would ask you for suggestions of how I could become more accepting of assistance, but I do not need your help.
