When replying to a loved one who asks, "Who did you play with?", it's important to be honest and provide the necessary information. You could say something like, "I had a great time playing with [Name of friend/colleague/family member] today." If you played a game or participated in an activity, you can add more information about your experience, like: "We played [game] and had so much fun together." This way, your loved one feels included and will appreciate your openness.
