My grandma did something like that once, she nearly burned the house down.. With a pot of beans no less.. My first dog is the only reason we still had a house and she's still alive, he woke her up.
eesh...way to go dog!!
I don't have a dog...but I have a cat that is a lot like a dog...I'm fairly certain someone out of the 6 people in this house would have noticed it soon if I hadn't...my husband said he could smell something burning but he assumed I over boiled something (happens a lot >.>) I can't smell anything right now...stupid allergies kickin my booty >.< but yeah...
I'm glad your grandma is still alive!
