Ok now....i dont think there is one person who doesn't like to dance. maybe the fact that they dont know how to do it make's them say such thing. But Come on!... In mi opinion, you dont have to learn to dance you just need to feel the music inside of you and let those feelings get out of you.
Express what you feel inside and have fun!. I'll tell you: I didn't know how to dance, no one showed me. I learn by my self, just watching those music videos like "Yeah" by Usher, "I'm still in love with you" by Sean Paul (oh this is my favorite! haha XD) and lots of videos you can watch people dancing and just having fun in
a club or a party. So come on! If you are afraid of what people may say of how you dance, its totally normal haha, but trust in your self and dont care what the other say. You'll se that with time and practice you will be dancing like a famous! Hehe Try it!.
