Doesn’t Have A Sunny Disposition

(After I explain to her that we can’t just move to Mars or Tatooine when the sun explodes.)

Sister: “So, when the sun blows up, will it blow up the entire galaxy or just a couple of planets?”

Me: “The galaxy has lots of suns. Ours will just take out the solar system.”

Sister: “I’m really worried about surviving the next hundred years.”

Me: “The sun will not blow up in the next hundred years.”

Sister: “But then I’ll be 112 and I’m worried about surviving old age.”
