Distracted By Golden Girls

I'm concerned with expressing my opinion in class. I feel like I'll just be mean or bossy when I'm rebutting someones answer. Its weird how I can never truly concentrate on thoughts or things when it's night time. I think I'm all concentrated out from school in the day. I'm using my brain at school trying to make cogent comments and articulating my view upon a issue. When it comes to ten o'clock at night I'm just spent and want to have my cocktail and watch Golden Girls.
