I believe there is an innate need for human contact and social interaction, which is why I enjoy being around people. Don't get me wrong, I enjoy my own personal alone time (I mainly enjoy the silence), but I really like to just be around the human race...well...most of it anyway ;o)
There are a few things that I just can't seem to do alone: going to the movies, eating out, shopping, and watching scary movies.
I am not a big fan of scary movies in general...but to watch one alone, are you kidding me!!! Not only will I have scary/freaky dreams for weeks...but I will also have a hard time falling asleep b/c the monster/ghost/alien/psycho will jump out of my closet/bathroom/window/bed and get me the second I close my eyes! But, if someone is with me, there is the slight possibility that I can run faster than them, or use them as a human shield.
I admit that I am insecure...but I try to see the glass as half full (my half) and conclude that I really really enjoy people...or dogs, they are a great substitute...and can't talk back!
