Special Delivery?

I'm going to tell you a story and then you're going to tell me if you think it's weird.  K?  K.

Last week, I ordered some Hunter rain boots from Gilt and I was impatiently awaiting their arrival.  I came home to my apartment and saw that I had a UPS slip on my door saying they'd been delivered (yay!) to the apartment complex office, but the office had closed at 6:00pm (boo!).  I made a point to go directly home after work the next day.
Sidenote: I have been living in my apartment since March 2009.  I have a terrible habit of buying goodies online, so I get a lot of packages.  However, I also work full-time so I'm never home during delivery hours.
I got to my complex office before 6:00pm (yay!) so I could get my new boots.  The UPS delivery guy was dropping off the packages for the day.  The office lady paused their conversation to get my package for me.  I politely said hello to the UPS man.  Here is how the conversation went:

UPS Man: Hey, I know you.  You sure do get a lot of packages.

Moi: [sheepishly] Haha, yes, I do a lot of online shopping.

UPS Man: And you're NEVER home.  Like ever.

Moi: Yea, I've got a job so that means I'm at work when you're delivering.  Sorry for the inconvenience?

UPS Man: So how's your Mom?

Moi: [Did he just make a "Yo Mama" joke? Why is he asking me this? What is going on?]

UPS Man: [interrupts] Because I remember you saying that she had surgery...I hope she's okay.

***Okay, people, he's right...she did have surgery.  In APRIL.  I have had one encounter with this man.  It was back in April after Mommy Dearest's surgery.  I had ordered something online (shocking) for her birthday (also in April) and there were delivery issues.  That's it.  That is the only time we have ever spoken.  I couldn't have picked the man out of a line-up if my life had depended on it.  

Is this creepy that he remembered?  Or am I just skeptical?
