I think it was when I was around 8, in 3rd grade, I wore pull-ups to school but was diapered at home because I had quit using the potty/toilet. I was invited to a friend's house for a sleep over, my parents were supposed to pack my pull-ups and well we ended up getting in a hurry and instead she grabed normal diapers and packed them and I didn't even get a chance to change into a pull-up. anyhow when me and my friend were playing I ended up tripping on a root because he had this big tree in the back corner and some of the roots stuck out of the ground and he came over and asked why I was wearing a diaper I was embarrassed and I couldn't even speak but he hugged me and told me it was ok if I was still a baby. he knew I used a pacifier during the day and didn't even care that I was the size of his 5 year old little brother at the time. we ended up inventing nicknames for each other, because we were very close as friends he called me baby brother because I was like the baby brother he always wanted again it was embarrassing at school too, especially when he would hold my hand as if I were a real little kid and he sometimes treated me like one. but he was that embarrassing older friend who you know has your back, he was 9 because he was kept back a year.
