How to Over Describe Random Sentences

Over describing school (Summer)

Inside a hot, stuffy class room, sitting on an uncomfortable plastic chair and a sticky desk. The teacher goes on for what seems like a lifetime talking about something to do with...I don't know, I wasn't listening. My mind is somewhere else, like the beach or a pool. Man would I love to just leap right into its cool, crystal clear waters, sinking deep until the very bottom. Yeah, that sounds nice. Or maybe frolicking in the waves, diving under the masses above. I could also relax under a pohutakawa (or any tree really) on my favourite beach towel, creating swirly patterns in the shaded sand. Then an icecream truck could roll by, and I'd buy my favourite type. Yeah, sounds like heaven.
"Milly."
Who is that calling my name? Sounds oddly familiar.
"Milly!"
There it is again. That annoying voice.
"Milly! Wake up!"
I lean up off my desk, rubbing my eyes. Soon enough, I realise I'm back in that hot, stuffy classroom, and that I had fallen asleep. I peer up at the angry teacher who stood before my desk with her hands on her hips and an extremely mad expression that plastered her face.
"Milly. I will ask you one last time. Name the two tropics of the world."
"Uh." Truely, if I had payed attention I would know. I glance around at my classmates, and even they look stumped, and worried for me. "Hawaii and Fiji?"
"Wrong! It's Cancer and Capricorn! Mrs Schmidt if only you had listened and weren't off in dreamland!"
I sat there for the rest of the class feeling like a sore loser, I swear no one knew the answer to that one. Maybe I should just forget about it and focus on the lesson. Man, would I kill just to be in water. To swim around the coral reefs and in the kelp forests in amongst the fish. Ahh... paradise.

My school has ended already! So yeah, I'm lucky! And if you are in the northern hemisphere, don't worry! I'll be doing one for winter.
