Seriously this happens ALL THE TIME! For exempel when I was in Portugal on holidays. We were on the beach and had an Swedish family behind us (we live in Sweden sooo) and the mother thought I was 18 or something. I was 13 at the time.
I am a scorpio. I never cry. I will never let you know if you hurt me. I will never show signs of loneliness or pain. You will never see a single teardrop out of my eyes, because you will nrver know me.
