When you’re a man doing manly jobs, your front pocket has things in them. I understand that being so soft such as yourself, you wouldn’t understand this. I get it, you have to sit down at your job all day, so you don’t want to have something back there.
I carry my wallet, keys, knife in my front pockets. I don’t want to fuck my phones screen up, so I’ll stick it in my back right pocket. Back left is typically reserved for a tool.
