answer:That’s such a great idea, although truthfully I’ve never seen a guy with a pinterest. But I would dearly love to know before dating someone if they’re on Reddit. Seeing their posts would be so informative. You know what’s another super sneaky way to find out what they want? Ask the person to help you pick out a gift for someone else in your life. Like, if it’s your girlfriend, ask her to help you pick out something for your sister. Then remember her likes and dislikes, and use it to find her a gift when you’re shopping alone.
