I'm not ready for Sienna to have her mom's sailor mouth, but eventually, when she's a teen, I don't want her to be afraid of speaking the language of her classmates and once she reaches adulthood, I hope to be ready for her to speak such words in my presence as part of normal conversation because the reality is that cursing is ordinary and sometimes, often even, acts as a release for pent up stress.
A really good friend of mine, a well-respected lawyer, in his late fifties, was late for his daughter's swim meet.

Profanity isn't shocking anymore. It's not edgy or sassy or hip or rebellious. It's just a sad, tiresome example of our shrinking vocabulary. Thanks, Twitter.
