The more important question is how the hell a 4 year old can get on a PC, unsupervised, and somehow access an online forum, of all things.
Real story by the way, let's get out of character.
My father was a miracle worker, he went from waking up 4 in the morning just to drive 20 kilometres back and forth to get some fresh vegetables to sell at home. He also saw, before I was even born, the wonders and future of technology, so he opened one of the first internet cafes in Vietnam and we got a stable life with a fine house now on that, he didn't have Youtube or shits to learn and he definitely don't have any mentor when you're the pioneer, so he just invest in a lot of computer stuff and yolo it. I got access to the internet VERYYYYYYYYYYYY early on, 4 years old might seems like it, I definitely got internet somewhere before I was in grade 1 (6 years old). He's also the one that pursue my brother into IT and the dude is now making more money than average even though he has 0 people skills.
If he were born in a more peaceful/well-fed era, he would have been in the ministry or sum'
