A bit different to the teacher making fun of me to the whole class by sitting in a chair, pretending to be catatonic several years later because I didn't have the answer for her rapid fire 9 times table (I was daydreaming and as is common my mouth was slightly ajar).
Not to say there wasn't problems; my mum used to send me up to get her a brush or some small thing and I'd forget once I'd get upstairs. After more than a few bollockings, I learned to ask where it was in the hopes it'd jog my memory. I was accused of not listening and I couldn't explain that it wasn't my fault!
I could however spend hours on Sonic 2 without taking a break. I was also infatuated with science and spent hours coming up with inventions that, to my dismay, already existed. I remember reinventing the fire sprinkler. It was more like a fire water balloon but the principle was similar.
These little memories, which form just a tiny grain of the daily struggle for the past 23 years, are almost funny. A joke, however, isn't so funny everyday, many multiple times a day.
When you discuss one small nugget, people say "ohhhh everyone was like that" and, due to lack of focus, you are unable to defend against their dismissal.
After 23 years, all day everyday, and the pain, hospitalisation and searching, dismissal by the ignorant is almost insulting.
Also, adding insult to injury, your use of the word "mum" suggests that you may have been forced to play the 50hz PAL version of Sonic 2 instead of the 60hz NTSC version.
