<human>: Can you provide a brief rundown of the text in within 3 sentences?

Back Story: I am 25 and work the health care. I have a friend who lives in an apartment complex near me, we'll call him Clyde. I went there last night to hang out and ran into a nurse friend from work there, we'll call her Morgan. Morgan's sister was moving in, we're pretty good friends and have been working together for like 2 years.We talked for a little bit and then texted about how weird it is that out of all places, people, and time, we ran into each other then and there. And how I knew which apartment her sister was moving in to because of the smokers that lived there just before them.

Anyway, now with the embarrassing part. I was walking my friend's dog outside around the complex to go to the bathroom, and Morgan's sister's apartment is on the ground floor. The dog got excited at seeing all the people through the window (she's a golden lab) and put her front paws on the window frame outside the window. I told her not to jump, but she doesn't listen to me very well, and she weighs like 80 lbs so i had to get her paws off the windowsill. I said "sorry about that" and pulled her off the window. Someone else in the apartment said "who's that?" and another closed the window right after.And I just got super embarrassed and kept walking the dog and walked away.

I'm not sure if Morgan was in there, or her boyfriend, and noticed it was me, they would be the only ones who would recognize me, I don't know her sister or her friends at all. Also this happened at like 8:45pm, so it was pretty dark already. Should I apologize via text? Or just not admit guilt and play it off like it ever happened? Though if they "do" know that it was me, and I don't acknowledge it, makes me kind of a super creep, right?
<bot>: Friend's sister moving into new apartment, they know I was in the area, dog put paws on their windowsill late at night, I took her off, but still might look like some weird window peeper/creep/etc
