Over the summer I met this person that I just couldn't get off my mind. 
Yeah? Tell me about them
She's great She studies Philosophy, which is ironically enough the study of the mind! Ironic because she's always on my mind. 
That's an interesting course, how long has she been studying it for?
She said she's been in college for about three years but is working towards a double degree. She said that the way our minds work can be influenced by events that we experience throughout our lives.
That's admirable. So a traumatic childhood experience would change how I interact with life now?
Yes, exactly. You can also sometimes forget those memories and not understand some of your behaviors that come from that event. That condition is called Dissociatvie Disorder. 
That's quite weird actually, are there any other childhood related conditions?
