It's not always bad to commit solitude, it is not always deadly to keep isolating yourself from people, I appreciate those who stay isolated at some times, because they got hurt a lot from people, I esteem them, cause their solitude has a noble reason.
Sometimes your solitude might be bad, especially if you don't have a single reason for it; for instance if someone stays isolated due to weak personality, or due to unsociability, that would be awful, if he thinks he's right being like that. As advice for all, stay alone to think to yourselves, stay alone to summon your strengths again after being hurt by the inside, stay alone to work on yourselves; but becareful staying alone because of weak personality, or unsociability; keep strong, keep sociable.
