If I wear casual clothes to my job, the people who like wearing formal clothes might say that I look ugly. Love is blind. Another example is between persons. If I like a girl and fall in love with her, for me she is beautiful, but for another man she can be unattractive. I remember the end of the movie, Planet of Apes .
True beauty opens locked doors.
Many people look for external beauty, and they forget about feelings. But in the end, when the beauty is over, the same doors will be closed.
