<human>: Obligatory 'this happened on Thursday not today.'

To give a little background, I have been working out at a neighborhood gym for around a month or so now. Sadly, I don't have a full length mirror at my place and the only one we have is in the bathroom where I cannot possibly checkout my lower half (especially since I am only 5 ft 2 inches). Me and my boyfriend have been planning to get a full length mirror for a while now but somehow we just haven't gotten around to doing it yet.

So anyway I have really enjoyed going to the gym and working out for the past month. I especially like to focus on my lower half of the body because I've always wanted a full, round booty that I do not have but hope to have one day. So I have been squatting quite a bit with weights over the past month and unfortunately, due to not having a full sized mirror in our place, I have not been able to monitor the progress and figure out if I have packed on any muscle in my backside. So this fateful Thursday night, after finishing a fairly successful leg day, I decided to go to the bathroom. This was at 10pm when the gym was supposed to close. Since it was already late, there were very few people in the gym and when I went inside the bathroom, I assumed there was noone in there because it was a fairly small bathroom with only 2 stalls and I didn't hear any sound from inside. I then saw a full sized mirror right next to the bathroom door and proceeded to turn around and pull down my shorts and check out my ass from a rear angle. Next, I don't know why but I just started grabbing my butt whilst still staring at the mirror to see if I had more meat on it. Right as I grabbed a big handful of meat from my backside, someone walks out from one of the stalls and is staring at me in utter shock! Needless to say I went red and ran out of the bathroom like there was no tomorrow!

Give me a shortened version of the text
<bot>: No fullsized mirror in my place, pulled down my shorts in a gym bathroom and got an embrassment of a lifetime
