Similar for me but instead i was counting seconds and calculating power of twos, both of which they found really creepy. My mom came to pick me up once and this was hungary so the nurses had no idea what numbers i was saying and they asked my mom what the numbers were and she was already used to it that point and just answered power of twos. After that the staff thought my whole family was insane. Thankfully i was a gifted kid which means i excelled academically until 8th grade where i burned out completely and since have done nothing productive in my life....

i couldn't count past twenty until I was around 5 years old, but the moment I figured the system out I knew I had found something more important to do during naptime than sleeping

Prepping for DUI checkpoints?

I hate napping as an adult, but back then? Nap time slapped.
