No, You Cannot Tell! Never tell anyone about your affair. The moment someone else finds out about it, you’ll be in danger of losing it all. It’s only normal to want to share the excitement, sing your lover’s praises and gloat about their sexual prowess but you can’t. Instead, talk to yourself when you drive. Write their name on the water when you bathe. You can smile that secret sated smile when you’re with friends, but you can only own up by saying you’re happy with your life, your work, or your dog learned a new trick. Read the book for more.
