Other side greener.....huh!

Why do our hearts sometimes yearn for change and when we have changed something, it yearns for familiarity. Like what you had was better. I miss the birds and the air of where I used to be. I miss the swaying trees that have seen me through some important events in my life. This place although warmer in reality seems colder. Maybe it will warm up in my mind, with time. My cats have adjusted and I wonder what their secret is. Things are so much easier and simpler in their minds. The human mind is very powerful and it will learn to adapt and change...again.
