Maca's dad lived with us (all of us actually) for a time. He's awesome and I love him to death. I just call him dad-but when talking to people who don't know that might be confusing (God forbid someone get the idea that Maca and I are siblings!
He's just a jewel. I don't know how I got so lucky to get such a wonderful father in law. He recently remarried and lives in NY so I haven't met my MIL, but she certainly hasn't been a difficulty!
