Input: Text: this happened back when i was in preschool. my uncle and his wife would often send us care packages from when they were living overseas. their care packages were often marked with "lots of love from uncle __ and aunt __!" written on the side of the box. since the boxes were pretty big, my mom decided to keep one of them to use as a place for me to store my toys. 

fast forward a year or two later, my uncle and aunt decides to come home and settle here instead. my uncle would always bring this nice beautiful lady to our house whenever he came to visit. i suppose you could say my parents were non-confrontational about it, since it's kind of none of their business. on one particular occasion, she sees me playing with my toys and asks me if i have any more to show to her. i ask her to wait right there and i pull out the giant care package box full of toys all the way from my room. 

the look on her face was priceless when she saw the box and what was written on its side: "lots of love from uncle ___ and aunt ___!" needless to say, we never saw her again, and i didn't realize why until a few years later. ( ͡° ͜ʖ ͡°)
