Trust Us, We Remember

Guess what? Your childhood isn't as archaic as you think it is. Lego is still in business. In fact, they're doing better than ever. They make their own movies now instead of building toys based of existing ones. Finding Nemo? You can get it from Netflix. People still play Red Rover at recess. Classrooms without ceiling projectors still use the mirror and light kind.
Everything you liked is still around.
