<human>: So let's set the scene. Earlier today, it was my Girlfriend's grandmother's funeral, and afterwards there was a gathering at my Girlfriend's parents house, where there was food, and drinks for everyone. Where everyone can reminisce and share memories.

So i'm in the kitchen with my girlfriend, her parents, her grieving grandfather, and other family members. My girlfriend has a dog, he's quite excitable, and likes to sit on people's laps. So my girlfriend's mother, says to the grandfather, you should take the dog home, keep you company in a joking way, people were laughing, the mood was quite light. My girlfriend's father follows the joke up with 'yeah he'll wake you up nice and early by jumping on the bed' More laughter follows. For some reason a dark joke popped into my head, sometimes that happens, but you normally you filter it out to something you should say just in your head. Well my filter forgot to apply and out of my mouth i said "It won't be much different, he's used to a bitch in his bed" It's not even a good joke, i know. So cue dead silence and what feels like a thousand eyes burning into me, me wishing the floor to just swallow me up. The grandfather burst into tears, and was quickly ushered out the room, my girlfriend's parents suggested i should probably go home. So i did and now i'm writing this TIFU. Girlfriend hasn't replied yet to my texts, the family couldn't look me in the eyes.

Can you summarize the given text in a few sentences?
<bot>: Girlfirend's grandmother passed away, the mother suggests to grieving grandfather to take the dog home with him, i suggest he's used to having a bitch around.
