Someone Named Joe is Putting Up Panicked, Handwritten Missed Connection Signs in New York

From one of our readers, a sign from a man named Joe. Joe is on a mission.

KELLY A

I'VE BEEN TRYING TO FIND YOU SINCE THE DAY WE RAN INTO EACH OTHER AT THE KEW GARDENS TRAIN STATION. I TRIED YOUR APARTMENT ON GRENFELL STREET BUT IT APPEARS VACANT. THIS IS MY LAST SHOT AT FINDING YOU. PLEASE CALL ME AT: [redacted]

-Joe

The sign raises a number of questions, such as:

Is it "Kelly A." or "Kellya"? There's no period after the A, of course, but there is an extra space after the Y. Which seems more likely? That the principles in this story are Joe and Kellya, or that Joe is papering lampposts with signs in order to find a woman whose last name he's not sure of?

Do you really think that this is his "last shot"? He's already visited her house and written (at least) one flyer by hand. Is he really going to just give up if she doesn't see these and call him?

Why is the entire note in capital letters except for "Joe"? Do you imagine him yelling the entire note, and then quietly whispering his name for emphasis? Does that make the note creepier or less creepy to you?

What happened at the Kew Gardens train station? Is Kelly(a) in trouble? Is Joe trying to help, or is he the reason she vacated her apartment on Grenfell?
