My worst school year ever

So basically I'm in my senior year, and I'll be almost done with high school year yay..but ugh why do school works has be so hard like do I have to do something to upgrade my grades up and achieve something? Will some dude chats at me this Friday night and I never know him in personal, but he saw me at school up course he saw me, but I mean he's 19 and I'm 16(I'm still a minor).

And than we chat a bit, and he had the audacity to ask me out to be his girlfriend like dude I never know you and you never know me ughhh, boys are complicated sometimes..
