I haven’t seen this ep yet but I think what one can surmise is everyone has a different way of studying and dealing w the stress it causes. He’s failed it several times and I can see how that would make one bitey. The show is her deal. If this were my household and I had kids and mr Natalie had a test like this I’d take over all kid duties and leave him the eff alone except bringing him food occasionally. It’s called teamwork. Maybe I’ll feel differently once I see it but I doubt it. Once I was an adult I didn’t care what day my bday as celebrated. As long as it was remembered.
