Offline vs Online friends

Why is it so difficult to make offline friends? I wish the real life was like the online one! You just download an app, post your interest and... BOOM!! You get friend requests from people from the entire world, and those people are just like you!! It's amazing!! Sometimes I wonder why does all the cool people have to be online friends and far away from you. Maybe it's because if two online friends meet each other it would be CHAOS !!! ( In a good way x3 )
