What have you learned about other people in life? (trustworthy, kind or not and mean)?

     There is a spark of the divine in each person.  In Eastern custom, when someone is greater, the hands are pressed palms together in font at about chin level, and a small bow is made.  The palms pressed together creates a shape like the sacred flame and when the Easterner does this, he or she is paying homage to the spark of the god that is in the person being greeted.  In Wester culture we do not greet in this manner, but it would be well to mentally do something of the kind.  Our ability to develop charity would be greater.  The amount of kindness and goodness in our circle of influence would grow.
     That having been said, we should also remember the caveat: Buyer beware.
     The council that Polonius gives his son, Laertes, upon his departure for school is good council, though Polonius does not follow it as well as he should.  Here is my council:
1.  Be a friend to all, but carefully choose those whom you will hold closely and dearly.  Chose them based on how they help you to be a better person.  It is important to be well connected in this world, but do not make connections that will cost you your reputation or your standards.
2.  You friends will have a great influence on your thinking, so chose them carefully.
3.  I have never been one who cared much for social climbing.  So, in situations where there are new people to meet, I usually gravitate to those that I can serve rather than to those I want to keep up with or get ahead of.  It has brought me greater happiness, and it has protected me from the influence of those who occupy the Great and Spacious Building.
4.  Social media will allow you to maintain many relationships with people you have known from long ago and far away.  Don't be afraid to express your opinion on social media, but do avoid the tendency of many to be rude.  When old friends post something that is hurtful, don't be shy about telling them or about just hiding the post.  I usually tell my friends when they have posted something stupid.  ("Stupid" does not mean something I disagree with; it means something that is rude and offensive in a real way.)  Be careful what you "like" because it will show to anyone of your friends that you "liked" it.  Mostly, it will serve you best on social media to keep a grateful attitude (avoid complaining), a positive mood (avoid being grumpy), an uplifting spirit (avoid the trash and the trolls).
5.  See others as their Heavenly Father sees them--with hope and compassion.  Each person who wrongs you or others or themselves, remember that the Savior willingly suffers for them and would want them to repent and to receive forgiveness.  "Remember that the worth of souls is great in the eyes of the Lord." But always be aware of who is influencing whom when it comes to relationships.  Be hyper aware of the influence that you have on others and chose to be closer to those who have a good influence on you.  How will you know if the influence is good?  Ask Moroni.  It is good if it brings you closer to Christ.
