Spellcasters and fairies: can they be friends

My spellcaster sim befriended a fairy and had no negative relationship at first, but they were both children. My adult spellcaster had a rough start with a fairy or two, but they were extremely negligible. Some didn't even start with a negative relationship buff.

All of these are spellcasters interacting with fairies first. It might be more difficult if fairies initiate things, since they're the aggrieved ones. But aside from that, it's not really noticeable for me.
