Scene Writing

I've decided the assignments I enjoy the least are the ones that require me to write a 'short scene.' I've always written my stories from beginning to end so that I can feel the same flow of emotions I'd want my readers and characters to experience. The author however must not feel this is very important (or that a writer can achieve the same experience without doing this) because she asked me to write a scene for three characters each where I describe their emotions through physical description. Then I needed to write a scene for one of them where they were feeling one thing but had to hide it for one reason or another. I didn't like the idea of this but it's the assignment so I wrote one.
Unfortunately for me, the assignment was helpful. It was good to focus on one scene including focusing on one skill. I realized I don't describe my characters feelings as much with physical description but with their thoughts on their surroundings. It was good practice but I still hated it. I haven't thought too much about the details of the scenes so trying to write four scenes for three different characters felt impossible. I can only think of one other character and moment to write about.
Today I'm spending the day with a friend of mine, enjoying the nice, summer weather before the storms come tomorrow so I won't be doing much writing today. I suppose I could do some tonight but I doubt it. I have a feeling after I walk around all day today I'm not going to want to walk all the way to the Starbucks that's open late to write some scenes I'm not looking forward to writing.
I will say though, possibly thanks to the fact I spend most of my days inside, surrounded by dogs, or toddlers, or my aunt, that leaving to go write has become something I really look forward to doing. In fact, a couple days ago I finished two assignments in one day! Maybe I'll actually have this book done by July anyway!
