Look you can be friends with the guy. But tell him straight , tell him on Email. If the guy understands what you are saying then he will respect that. You have to say it straight . When you look for somebody who you don't feel may have the same INTEREST or age that you are looking for, then tell him straight. But the biggest way to tell If he really read your profile, put on your profile what the age limit that you want . If he still gets back to you after you had placed the profile like that , then you will know he is fake
