What’s wrong with talking to oneself? Kids always do that. Maybe they are talking and playing to their Guardian Angels or Archangels. That’s a healthy thing. You know you are even talking to yourself more than you know it. Every day you are constantly talking to yourself but you are just ignoring it coz others would think that you are weird. But really talking to oneself is a healthy thing. You are talking to your inner child. Come on men! Just leave the kids when they are talking to themselves because when they are hearing you talk to yourself, they will not say a thing. Nyaha!
