What was something that you thought was amazing as a kid but was actually a little/lot messed up?

One thing that comes to mind is diet coke. So my mother would never let me have any, not even a mouthful (around 6/7 at the time), and she brought it a lot. But she would never empty the 2L bottle, there was always some left over sometimes it was about half a teaspoon, other times she would reward me and give me a finger's worth, she used to make it so exciting. "Mummy's letting you have her dregs, remember I could have drank it all myself, but I saved some for you," I was so happy that she thought of me and saved me some. I remember keeping a bottle (small 500ml) in my wardrobe and over the course of two, maybe three months I would save all the dregs and it would be a full bottle. Over the course of a week I'd slowly drink that bottle, so proud that I had my very own bottle of coke.

When in actuality the reason she didn't drink it was cause its gone flat and she hated flat coke. She also brought a bottle every 2-4 days and it still took months to fill another bottle. I remember one time telling my dad about my achievement, and he got soo pissed and at the time I just couldn't understand why. But when he went into the shop and said I can pick whatever bottle of drink I liked, I gasped and said really? I still didn't believe it at first cause there's been so many times my mother said I can pick something out, then got to the till and said sorry baby I can't afford your drink or sausage roll, (while still affording to buy a pack of 20 fags and her 2L coke of course).
