I do now.
I'm extremely critical by nature, so used to be aware right away of people's shortcomings, especially if I took an immediate dislike to them.
However, age has mellowed me and caused me to realize that if I wait long enough and keep my judgements to myself (which I've learned to do anyway), eventually something about the person will surface that I will like.
I also know how painful and demoralizing it is to be judged and found wanting myself, so really don't want to lay those things on other people.
