This one time i went to Costco with my little sister and we both had to use the restroom so we both went there. I saw her get into a bathroom stall and i decided to get in the one next to her. As i sat down i decided to mess with her, so i stuck my hand from under the stall and started tickling some feet.......After a while i heard my sister call out, "Where are you?, I already washed my hands and i want to leave." I was tickling a random woman's foot. I then left, Well Happy Birthday and I hope you have a great day!!!!!
