Creepy Or Just Detail Oriented?

I'm a detailed oriented person. I focus on the small things that people over look. I look for the things that most wouldn't think to look at and am very good and putting things together. It's how I've been naturally all my life, it's how I catch people lying at work, and it's what's required for me to do well in the Computer Forensic arena if I want to continue along those lines in my career path. To get to the point of this post....

A few weeks ago a coworker and I decided to go to lunch on post. We decided to go eat at Popeye's, the best friend chicken on the planet. I was excited for more than just the chicken. There is a girl that works outside at the gas station on post. I don't know her name, but I feel like she looks like a Beth.

Beth is about 5'7, if I had to guess maybe a size 6-8, and 135lbs. She wears painted on black pants and her uniform shirt for the base gas station. She has a small diamond stud in her left nostril. Green eyes. Dyed jet black hair, that's cut short to about her jaw line, layered where it's longer in the front of her face than it is in the back of her head. She has a few freckles that cross over her knows and cheeks. Perfect white teeth. Nicely shaped lips.

I told my buddy that my "girl" will be walking into Popeye's in a few minutes. He looks at me jokingly and says what do you mean? I said...my girl "Beth"...she works outside, she comes inside around 1115-1130 to use the restroom and text on her phone.

Buddy: "You can't be serious right, you know when she comes inside, kinda creepy man, almost stalkerish?"

Me: " How so man? You know I'm detailed oriented. It's a pattern, I've noticed her before because she's hot as fuck and has done the same thing twice, so, I'm just assuming she will do it again"

Buddy: "Whatever an, no way, I bet you're wrong."

We get our food and sit down. I look up...and there she is...walking inside, along the length of the window, by our table and toward the restrooms. Look at my phone, time is 1123. We get a good laugh. She comes out and hangs out (and I feel this is purposely), not 5 feet from our table and starts texting on her phone. Her ass is just screaming in those pants, thick, meaty, juicy, has that perfect lip that hangs over that I want my hands to slide into you. She moves forward some and stretches near the windows and then makes her way outside again.

My buddy reminded me again that he thought it was creepy that I know a total stranger's pee cycle lol. I guess on the outside it is odd, but if you know me, it's really not that far out of the norm. People are creatures of habit and routine. It's how we feel structure in our lives, I just happened to pick up on a small routine of hers because she is highly attractive to me.

So strangers...is that Creepy or is that just part of my personality traits coming through?
