Yes I agree with you. When we are sad, we need to admit we are sad. Let sadness out sometimes and at one point, people just start getting over it and looking for next decision. However, don't be sad too long because if people get into too much sadness, they become deeply depressed which is not good. I think traveling is another way of dealing with sadness. Many people after traveling start finding different perspectives towards what made them sad in the first place.
