<human>: Okay so I live with my grandma while I'm going to classes, she had part of her brain removed so her motor skills aren't the best; as a result she needs 24/7 assistance and on the weekend that is what I do, unless a family member comes to help out.

This particular family member is my grandma's brother, my great uncle. Well, shortly after my grandma woke up and he was settled I went back to my room to avoid any awkward silence and played some video games. Video games have a habit of making me hungry so I went into the kitchen to fix up some ramen and I overheard part of a conversation my uncle and grandma were having, "...all I saw was flies, they got there so quickly." 

To which I responded by saying somewhat excitedly, " I KNOW! Maggots get into everything! I remember I was walking my mom's dog and when she took a crap the flies came out of nowhere and were on it instantly! It is crazy how fast they show up!"

There was a bit of silence and my uncle's head droops a bit before my grandmother promptly says, "Oh, he's talking about his ex wife." I was confused as he continued on the subject, "Yeah, I walked into the house and all I saw were flies coming out the bathroom, its how I knew she was dead."

Silence again before I awkwardly say, "Oh." Then grandma starts asking him if I ever met her as I sort of just slink back into my shell of a room to again avoid awkward silence.

Can you condense the text into three sentences or less?
<bot>: Be careful when you catch someone talking about flies, you could be comparing your late aunt-in-law to dog shit.
