Being a man means having more responsibilities in your life.
Yeah sure, some will say having a nice car and lots of muscles makes a man.
But what really matters is whenever there's trouble or something has to be done, you know exactly the guy who will be up for the task, be it taking care of the household or being the group leader at the workplace.
Even if said man doesn't want to do it, deep down he knows if he doesn't do it, nobody will try to fix anything.
