Theory: Absence Makes the Heart grow fonder / Out of Sight, Out of Mind

Some people say that this is true. Personally, I think that once someone is out of sight, one of two things happens (saying that 1 is one person, and 2 is the other):

• 1 begins to think about 2, and thinks of all the good times, making their memory in essence, "grow", becoming greater than life. The heart grow fonder in this way.
  
• 1 doesn't really think of the person much, but from time to time, they do see something that triggers the memory of the person in question, still making them remember, though they don't dwell on it. This doesn't really make the person more important to 1. 2 is just same old 2, no different than he/she was X years ago...
• Going back to the first of the three theories presented that I believe in on this subject, I believe the following is the most interesting. After some time, 1 forgets the little things about 2, and, being the person who does dwell on these things, 1 begins to worry about, let's say, 2's eye colour. Then, because he thinks of 2 so much, the first theory comes into place, and 2 becomes more larger-than-life.

I think that's, kinda interesting, all the same. Also, it seems obvious that I believe the opposite for "Out of Sight, out of Mind".

I'll try to post more frequently in the future.
