My sim's Mother-In-Law randomly kisses him in front of his husband. (The Sims 3)

Sorry for the not great video, but I tend to speed up actions a lot when playing, and I never really expect to get clips for this game. I thought this was funny though, so I clipped it.
CONTEXT:
My sim, Elijah is married to Leighton Sekemoto. The couple lives with Leighton's elderly mum, Yumi. The whole family got up in the morning at the same time, and I was mostly controlling Elijah and Leighton as I planned for them to get ready and then go out on a nice date together. Yumi has the inappropriate trait, and as I was not controlling her, she decided to walk into the kitchen as her son was making breakfast, and then proceeded to kiss his husband in front of him! Weirdly though, Leighton didn't really seem to mind, or even notice!
