Whoever it was, they had a beautiful way of describing people's tendencies to be jealous of others.
I was watching "Rizzoli and Isles" on TV last night, and the friends were each unhappy with their mothers. One's mom didn't really take an interest in her daughter, and the other took an over-active interest. However, they both appreciated and wanted a mom like the other had.
Whether it's how involved our parents are to our body image to what kind of home we live in, we all have a tendency to want what other people have - even if those same people are looking at us and coveting what we have.
When you start to get jealous of anything that you don't have today, stop and say a quick prayer for what you do have - even if it's not perfect.
