<human>: Summarize the given text in a few sentences.

I'm a university student and have just come home for the summer. My parents recently moved to a new house and still have contractors working on a new greenhouse. I go for long runs on the weekends and had just come back and was feeling really hot and sweaty and decided to strip off and take a shower. Unbeknownst to me, there was a contractor taking measurements outside and since he was quiet and I couldn't see him out the window, I had no idea he was there and thought I was alone in the house. I pulled off my clothes in my bedroom, walked to the lounge where the storage cupboard is and bent over to get my towel out of the bottom drawer when the builder came in to see me naked and bending over with my ass in the air. I heard the door open, spun around and let out the most ridiculous scream I've ever done and the poor builder choked out a "Shit, shit, sorry, oh my god," and ran back out again. He's gone now and I have no idea how I'm going to tell my parents. This guy is going to be at my house for the next eight weeks almost every day and I'm probably hiding in my room for the rest of the summer.
