Kinda got to agree with this, minus the grandson part. xD Professor Oak gives out Pokémon and Pokédexes to new trainers all the time and sends his aides out after you to deliver you sweet items like EXP Share, and he always greets you with a warm smile and friendly greeting. Plus when you're a new player in the Johto region he instantly befriends you in Mr Pokémon's house without even knowing you and throught the whole anime he's constantly helping out random Pokémon and making sure they're happy, so yes, Professor Oak is not only the nicest person in the Pokémon Universe but he's also the most sweet and amazing. Let's just give him a knighthood tbh. Long live Sir Oak!
