Maybe.

Maybe it is because I went to bed too late last night.

Maybe it is because I had to get up early. 

Maybe it is because I had a really stressful day at school. 

Maybe it is because I'm not going to have a life this semester. 

Maybe it is because I'm nervous.

Maybe it is because my apartment is 95 degrees.

Maybe it is because my ward consists of almost all freshmen....girls.

Maybe it is because of that phone call. 

Maybe it is because I miss you. 

Maybe it is because sometimes you feel alone even when people are around you. 

Maybe.
