<human>: Can you condense the text into a few key points?

So, me and my partner go out to the mall because she needs some food for dinner and while we're there we see they have a robot zoo spread out in a ton of little areas with robot animals. We pass a Robo-Rhino and theres a bunch of little kids like "HOLY SHIT THIS IS THE COOLEST THING EVER". My partner makes a passing comment and says "ahahah thats so cute, i bet they think that dinosaur is the coolest thing ever".

She immediately realizes her mistake but that doesn't stop me from laughing like a retard. She punches me in the arm and says im an ass. Later one, we pass by it again and all i do is smile like a retard at her. She gets REALLY annoyed and says "No you do not pretend you aren't giving me that shit face grin for no particular reason". I laugh it off and say sorry.

Finally we're on our way out and we have to pass by it one more time. Immediately, i keep my mouth shut, no grin, no nothing and just try to keep it normal as i know if i do something again she wont be happy (She really hates it when she does something stupid because she actually thinks she IS stupid, girl be smarter than me). But just as we get to it, it hits me. 

Just as we're by it and she thinks shes in the clear, i remind her she has a shitty choice in partner and immediately and loudly begin to hum the Jurassic Park theme. She doesn't say anything, nothing at all, and simply proceeds to speed up so i of course match her pace while continuing to hum. She didn't say a word to me at all and had the worst expression id seen on her in awhile, and the car ride back was just absolutely dreadful, until i tried to hum it ONE last time to see if i could break her out of her funk.

I am not a very smart man, anger was had, didn't talk to me for the rest of the day and was sour with me the next day.
<bot>: Girlfriend called Rhino a dinosaur by accident, i made her feel like a massive idiot by singing the Jurassic park theme, was in the dog house.
