What do you think about me missing my morning class due to oversleeping?
What caused you to oversleep and miss your morning class?
I drank alcohol with my friend and we got drunk.
It is fun to drink with your friends, but you should not get so drunk that you oversleep and miss your classes. You need to take school more seriously and miss no classes.
I'm a senior and I'm not sure if anyone cares
While people won't care for you, that is because you're the one spending for the school. You need to take care to not miss your classes and take it more seriously or else you might fail.
