I learned that you cannot make a square peg fit into a round hole. If it does not fit, you cannot force it. I believe I picked that up on Sesame Street. Or maybe that was from the game Perfection. I cannot really be sure.
I learned that only one person should talk at a time otherwise no one was being heard. I also learned by watching my mom then nothing is more important than taking care of your household first. That means it all I do is dedicated to my daughter. Anything else that comes along falls in line after that. If that is a problem for anyone, then they can continue on about about their way. I put nothing in front of my house because no one would foresake theirs for me.
I also learned by Kindergarten that I like to play outside. I liked to play with other kids. I liked dirt. I enjoyed playing with Barbies. Therefore I learned to cultivate a variety of interests. I don't rely on one person from my source of entertainment or my connection to the world. It becomes really sad to me when people don't have any outside interests other than their significant other or spouse.
So with these things in mind, I have come to assess the state of my relationship. If you must choose between me and someone else -- by all means -- pick the other person. I am not a choice to be made. You just don't happen upon people like me every day.
