I mentioned the bit about wives having phones in their purse. I used to get annoyed at my wife when I would repeatedly call her and get no response - she would claim the phone was in her purse and she couldn't hear or feel it. After we got a pair of Apple Watches, no more problems. I text or call, she feels it on her wrist, rolls her wrist and responds. You can talk directly via the Watch, or dictate to Siri to send a response. When driving, I tap my Watch and tell Siri "Call my wife", it does so and we carry on a conversation via the Watches. No more fumbling for a phone in her purse.
