I hate it when people say the sans fight is easy because once you learn his attacks they are easier to avoid.

That’s how every boss fight works, dumbass. It’s easier said than done though, and besides, you have to die a lot to get to the point where you learned every attack and can avoid it, so you can’t call it easy at that point, can you?

It’s like saying sports are easy because after years of practice and failing you get good.
