Friday night

It's Friday today! I like going out on Friday nights and also I like staying at home, too.
I usually have homework of in my English classes and study for the Cambridge exam. I'm going to take it in December so I have to study hard.
But I don't have any homework on Fridays so I can relax. I drank a bottle of beer and had a nice dinner at home tonight, so I'll sleep a lot tonight!

Pretty well written! :D

Just remember that if you refer to an activity as something that ALWAYS happens on a Friday, we use the plural "Fridays" to say that it happens every Friday.
