Lesson 1:  When we are close friends with someone, we often have expectations that can cause us frustration if they are not met. If a friend fails to act toward you in a manner you would wish, word your requests in a positive manner otherwise it can put a strain on your relationship and cause onaas devarim. I.e "why didn’t you call me in over a month? this shows you really didn’t care...". Instead "I really enjoy talking to you you must have been very busy lately...".

Lesson 2: We should be careful not to disparate the Torah thoughts of other people. You dont have to agree with them, but hear them out, learn... and be polite.
