Remember Me?

I am the rickshaw puller who took you home safe last night. Or the security guard, sitting outside the ATM booth, making sure that you have a secure money transaction. I am the cleaner who makes your office lobby look all shiny. I made you tea the other day in my small roadside shop. You met me once, or more than once. 

But you don't remember me. 

Because I belong to everybody and I belong to nobody.
