Just imagine, for a moment, that you are standing in a grocery store. You're wearing your favorite blue t-shirt that has the letters K-R-O-G-E-R embroidered on the short sleeve, and you're standing behind a cash register (Yes, you are a cashier, no it's not really important to the story.)
You are monotonously sliding things across the scanner while making idle conversation with the customer in front of you. It seems like a normal day.
Alex From Target walks by.
You make some more idle conversation with the customer. And finally they leave. (And of course they are extremely satisfied with their shopping experience because you are a wonderful cashier!)
"OMG OMG OMFFFGGGGG!!!! THAT WAS ALEX FROM TARGET! AlEx fROm tARGeT JUsT walKED By!!!!! DIDYOUSETHAT?!?!" (exclaims a courtesy clerk who has run all the way from the other end of the check out area)
The answer was no. You didn't. Because you were imagining you were me, and you were being a good cashier while you just missed the opportunity of a life time to get your best friend an autograph from a teenager who was on the Ellen Show because he got famous for BEING A CASHIER.
Moral of the story: Life is full of missed opportunities and sometimes you just gotta accept that you will be disappointed that you go to school a block away from the school that Alex From Target supposedly goes to, you even take a language arts class at said school, and you've been to that Target so many times because you just love Target so much, but you're never ever gonna meet the legendary Alex From Target.
