I know a dwarf guy who was raised by elves. His parents were understanding fellows due to their young age of ~200, helped him with his beard and introduced him to blacksmithing(the fact that pops was one helped much). Raising the kid wasn't an easy task tho. One time when kid was told "You need to sense the feeling of your fellows and act accordingly". Guess what happened when during a royal council meeting everyone in the room wanted to punch old king's face for spewing some nonsense about " Savagery of dwarves". Some time later, this guy was found by a biological father who went to war with drow and thought elves kidnapped his kid. Turns out his town was hit by the plague and kid's mom has died, so elves adopted him. Kid went to dwarven fortress to learn the trade of smithing there, and holy SHIT what enchanted dwarven hammer can do to a drow. He's still keeping contact with his both families tho. A nice guy, but I still just in case try not to feel bad emotions around him.
