fourteen's not really too young. i started about that time too (i'm almost 16 now). why are you afraid for your mom to see? but anyways unless the foundation is waterproof then it should come off with soap and water (or a good face wash will help). to remove all traces of the mascara try using baby oil (i'm guessing you have that somewhere around the house?). if not then vasaline works too but it's slightly more messy. good luck :] ?
