Mommy, can you buy me a new outfit?

Alright, so I encountered a mother and son pair at work that really made angry and inspired this current rant.
So it was a slow day in the store and I was desperate for sales. This slob of a man walks into the store and he looks completely lost. This grotesque, overweight man stood there wearing his unlaced Tims, extra baggy jeans, Roca Wear jacket with fur trimmed hood, and fitted, completely bewildered by the fact that he was standing in a store that sold khakis, polos, and other formal wear for men. I walk over to him and asked if he needed help. He tells me that he is looking for khakis that will not wrinkle. I direct him over to where we have those pants and he hurriedly walks to the wall. Then his elderly mother saunters over with her make-up perfectly done and hair curled up ever so classy. She explains to me that her son needs some pants that can take a beating because she is tired of buying him new pants that do not last. I reassure her that she has come to the right place, but I inquire as to what her son does for a profession. She tells me that her son does not need the pants for work, but to go "clubbin." As soon as she tells me that, I think to myself, "What the hell is going on here?" However, all she saw me do was smile in agreeance and say, "Oh."
Now this whole incident pissed me off. I cannot even fathom the concept of being in my late 20's or early 30's and having my mother buy clothes for me, especially clothes she feels I should go out in. I have been on my own for so long and handling my own business for so many years that I wouldn't want to be treated that way. In fact, I've been keeping my family afloat instead of the other way around. A lifestyle such as that would break them.
Really though, I know this is not an isolated incident. There are way more of these coddled, overprotected slobs out in this world who have no idea how to live for themselves. This is one of the problems with society. Guys like this are still suckling at the teet of mom and dad and are unwilling to let go. What makes this even worse? These are probably the guys who have the utmost confidence in themselves, yet have nothing going for them. It's quite sickening.
Well, it appears I'm done ranting and ridiculing these losers, but I have come up with a question for anyone reading this. How can somebody go through life living for nothing?
