WRINKLY FOREHEAD is a character in OMORI. WRINKLY FOREHEAD is an elderly man dressed in a pale uniform. He can be seen regularly cleaning up around FARAWAY PARK as the janitor. He's also JESSE'S DAD, a single parent who loves his son a lot but you can clearly tell has a generational gap when trying to connect with him. He doesn't understand JESSE or JESSE's interests, but he's doing his best to support him as much as he can--even when their family doesn't have a lot of money. [some description pulled from the OMORI Wiki]

PREVIOUS NOTE: JESSE'S DAD is one of my personal favorite parents from the game. He is clearly doing his best, even when he doesn't understand. Even when he makes mistakes, he tries. He should sound older, because he is than most other parents, but not grandpa-age. Anywhere in the medium pitch range is fine. 

ADDITIONAL NOTES: While being careful to not sound too old or grandpa-ish, try to sound like a well-meaning older man who cares a lot but is clearly from a previous generation. An accent is fine; what matters most is how earnest he should sound. Like previously noted, anywhere in the medium pitch range works.
