<human>: Can you succinctly summarize the text in 1-3 sentences?

Happened 15 minutes ago. 

 So I'm running up and down the building stairs and sometimes I like to climb up the roof and just sit there, either drink beer or listen  to music and maybe meditate. 

Today was as usual as any other day that I'm doing it, I'm on the building listening to music and I decided to share some scenery with my friend as its 9pm and the night is beautiful. 

I should note now that in a building in front of me, there is a party on a penthouse. 

So I'm taking pictures of the night and I took some pictures with FLASH on while photographing the roof. 

 Not 2 minutes later I hear the music stop at the penthouse. 

5 minutes later 2 buffed up dudes come up the stairs and open the roof door, we lock eyes and they start shouting about me to "stop taking pictures of Leila and get the fuck out or they'll break my bones. 

I look at them with a confused face and tell them that I will. 

Apparently some celebrity or something was having a party and they thought I'm some kind of paparazzi. 

Lesson learned : don't take any pictures at night from a roof with flash.
<bot>: went on a roof at night to snap some photos, I did but with flash,  2 bouncers threatened to kick the shit out of me
