Interesting question. Well, I think that everything can be determined through the person's closeness to you. When you get praised from someone, ask yourself "Why did they praise me?" Also, sometimes, people may tend to praise too much because they want to be praised in someway as well. Possibly, if the person is jealous from you because you are better in someway, they may try to praise you in order to affirm to themselves that they are not jealous. This is a tough question. I hope my answer helps!
