I get to hang out with friends in school. The school atmosphere is usually less tense. It takes the pressure of knowing there's homework next time for quite some time. I can get home and relax. There's youth group <3.
Friday. It's the end of the week, there is still stuff to do and things to be done but at the end of the day the night is yours. The energy is usually pretty high and exciting so in general it is just a fun day. I usually have some degree of feeling "a job well done" on friday.
Friday, because the mood is very light and celebratory. Also, my family has a tradition of eating pizza and renting a movie every Friday. It was also the day I was born on, and the day when the most happy memories in my life took place. I would say Saturday, but my family is usually crabby on Saturdays, so I spend most of the day wishing it were over.
