Don't judge a book by it's cover…an old phrase that I have heard, and said, countless times in my life. But the reality of actually putting the principle into practice is a whole different story. Like in this experiment:

What an enlightening moment! I think it is in our nature to make judgements about people and their situation, but what opportunities might we miss by judging too harshly or too quickly? It is easy to say that I would never find myself in the same circumstance, but given similar life experiences, how would I measure up?

Appearances can be deceiving.  In an address to a women's conference, President Thomas S. Monson gave this talk: (Note: This talk is almost 20 minutes long, but is well worth the time spent listening:)

What wise the council he gives! We all have plenty to work on without being critical of others. There is a scripture in the Doctrine and Covenants, that says:  

123 See that ye love‍ one another; cease to be covetous; learn to impart one to another as the gospel requires.

124 Cease to be idle; cease to be unclean; cease to find‍ fault one with another; cease to sleep‍ longer than is needful; retire to thy bed early, that ye may not be weary; arise early, that your bodies and your minds may be invigorated.

125 And above all things, clothe yourselves with the bond of charity, as with a mantle, which is the bond of perfectness and peace. (D&C 88:123-125)

I am frequently reminded to be as patient with others as I would like God to be patient with me.  We must never dismiss the value of any soul, for all are great in the eyes of their Heavenly Father.  I can always stand to work on my own windows before venturing a comment on anyone else's laundry.
