When my (Jethro's) mom and Staci's dad told us they were getting married, Katya was close by but didn't say anything. I said, "Katya, did you hear that? Grandma and grandpa are getting married!" She stared at them for just long enough for them to stay completely focused on her, and then, when they were about to talk about something else, Katya said, "Awkward!" then laughed and ran away.
It was brilliant.
