Opinion is what someone thinks is right or wrong. Honest observation is what you see understand or how you came to know something. My grandmom always tells me to go to church and find a good pastor. I think she means one I like that speaks to my heart. If you go to 4 churches before you find the right one, your observations of what you liked and didn’t like are honest personal observations, not opinions. In my opinion, thinking smoking is wrong or bad is an opinion.
