Ramadhan has come..

Ramadhan has come...I've been waiting for it for a long time...Finally,it come..I love ramadhan cause it's a great month and after that,raya comes...I love both of them...Now,I'm hungry because I can't eat...I'm so tired..I'm tired to type but I did it...There still a couple of hours before the time to eat...Today,my mom told all of us must go to the tarawih solat....I don't think I wanna go cause I don't know how to do..My mom said just follow..But it wouldn't be sah cause I don't know the niat...I DON'T WANNA GO!!!but my mother refuse me...what should I do??
