you missed a good chance their. you could have gotten play dough, and made up little horsey figures, and put them on your desk from "the kids" gone to the park, and stopped parents and told them their kids looked like your sisters kids, and gotten pictures with them. or taken selfies with un attended kids. [bit of a dangerous thing, but thats part of the thrill] and then after a year, swapped them out for new children, just to see if anyone would note.[ wait, diddnt they have red hair and freckles?]..it can be an adventure. i knew a lady who had a mysoginistic boss who considered womens periods as bad juju. she said she had 3 "periods" in a month one time with out question from him. she would just go in and say" wow, i gotta go home early, cause im bleeding like a stuck pig"
