['I got a scary call from my nieces earlier this week. Apparently no matter what they did, they could not awaken her from her sleep.', "Wow, that must've been awful! How did it all turn out?", "I apologize, they couldn't wake my sister up.  Thank God she ended up being okay, the EMT's checked her out...we have no idea what happened."]
That sounds really scary, I'm so glad it all turned out fine.
Last Wednesday my nieces called me to let me know that my sister was lying in bed and that they could not wake her up no matter what they did. She ended up being fine, not sure what happened.
