when I was very young, probably like 5 or 6 I went to my grandmas for the first time in Michigan. She walked me over to neighbors because they had kids and there was this redhead girl that was a little bit older than me but not by much. My grandma didnt know who she was but just left me with her, she said lets do a prank! And I was shy and just went with the flow and she took me to this house down the street. there were no fences in backyards in this suburb by the lake. We went to sliding glass door in the back and it was unlocked. She thought it would be funny to hide in there like hide and seek! So we went in really sneakily and went into the bedroom and hid under the bed. I vividly remember looking out from underneath the bed and hearing the door to the garage close and a woman walk in. She came into the bedroom and walked all the way around the bed into the master bedroom bathroom and closed the door. Then me and this girl snuch quietly out from underneath the bed and snuck out of the house. I didnt remember this until much later and now it seems super creepy and I dont tell people this story due to how creepy it sounds.

tldr; As a very kid I snuck into woman's house, hid under her bed and watched her from under it, then snuck out with no one seeing me.
