3. Sometimes When You're Sad, They'll Give You A Scientific Reason For Your Emotions Instead Of The Sympathy You're Sure You Deserve
What you think of as the happy messengers in your brain are what your partner calls the Biogenic Amine/Endorphin system - and when you're crying because The Theory Of Everything was just so overwhelming and so good, the last thing you want is them telling you that your Endorphin System isn't keeping up with your stress overload and you're experiencing a brain chemical imbalance. Goddamit, all you want is a hug and big bar of Galaxy to put the world back to rights. (That's not to say your S.O doesn't give you the love you need. They just sometimes get a bit carried away with the scientific jargon bit because it's been waiting in their brain to be verbalised).
