Hey! Isn't this freaky?! i saw myself in the future...?

hey! so, im 13 and i went to the mall the other day wih my friend. We stopped at Auntie Anne's pretzels because i LOVE that place..haha.. So anyway, im on line, and i step up to the cashier, and she looked at me and i looked at her. She looked exactly like me! same wavy brown hair, same brown eyes, same way i wear my hair! my friend said it was scary because we could have been twins! i looked at her nametag and it said the same name as mine, GRACIE!! and i noticed she was wearing aquamarine earings, same as MY birthstone, and she was wearing convers snaekers, which i practically LIVE in! only thing different was she was like 17..and im 13.. but it was scary! we just like looked at eachother for a minute and like it was weird..haha..idk, i don't really know what to make of it..do you think it was some mystical magical event or just coincidental?! comments please! no mean 1s tho, they will be ignored (= thanks!!
