I have nothing to say 

or do I?

that's the problem 

I'm not sure

 but that's not interesting

 no one cares about nothing 

or about being unsure

it's weak

and uninteresting

 everyone has something to say 

 I know because I hear them

saying stuff

 like the guy with Boston Bruins jacket

to his credit he didn't talk about hockey

 what did he talk about

I don't remember

so it couldn't have been that interesting
