Let say you know person A, who've always called you by a special nickname. One day they suddenly call you by your real first name and you freak out. They then proceed to tell you that they've got the wrong number and hung up to call you back again. They then tell you that they got the wrong number because they also have another friend with the same name and similar cell phone number, who is also the same sex. What are the chances of this happening in real life and does it mean anything?
