The Thought or It

A friend told me once, that we sometimes struggle with distuingishing if we actually like someone, or if its just liking the thought of liking someone. We sometimes set our hearts on things that are just thoughts, and sometimes throw away the things that are more than thoughts. I look at everyone around me, and have learned from their mistakes. I have learned from my own. I don't believe it is the liking part that is that hardest part, but choosing if it is just a thought or more.
