I love the show Bones. The main character Temperance Brennon, any time she doesn’t know what others are talking about she says “I don’t know what that means.” I totally stole that. I say it all the time.
It has helps me ask more questions when I don’t know what something means, or I don’t understand something someone says. I also look words up when reading books, articles, etc that I either can’t remember the meaning of at the moment or I don’t know.
I love learning new things. From reading or from other humans. You can learn something new from any person at any age. Just because we are older doesn’t mean we know everything. Always keep your mind open to new things.
