alot of ppl out there think that sans is the older brother... (around 20-30 but over 21 maybe idk) the creases under sans's eyes explain it and papyrus might as well have gotten growth spurts as a kid, not in age but in height. alot of older people out there can sometimes but not always be lazy like sans while the younger ppl tend to be more energetic like papyrus.
