Mom-dad
Gender can be a sensitive topic, unless you’re talking about it with people you’ve known all your life. It’s only the ones we hold dear in our hearts who can make light of gender jokes, though we’re not sure this mother (father?) would’ve approved of their son’s sigh.
This person was more than willing to go to the airport with a congratulatory sign for their mom-dad after she/he underwent gender reassignment surgery. The look on this person’s face says that he doesn’t fully understand it, but he’s accepting of his mom-dad’s choices anyway. It’s important that we keep an open mind and maintain our sense of humor, folks.
