I accidentally left a diaper at my parents house when I was visiting them at some point. I live out of state and go back for the holidays. I'm usually very good about not forgetting anything and always double check everything before I leave so I'm not sure how or when it happened. My mom found it and gave it back to me when I visited again. I'm pretty sure she already knew because back when I was still living at home I usually kept my diapers in the back corner of my closet behind my hanging cloths. One day my mom being the loving mother she is hung up my laundry for me. She would have to have seen the diapers to put the clothes back but she never mentioned anything.
