There is always a place, and a time for sentimentality. Sentimentality serves a very good purpose in that it encourages us to remember people and events that were important to us. However this does not mean that we should allow our decisions to be based solely on sentimentality. For example, let's say someone gave you an expensive watch. You care a lot about the individual, and so you are reluctant to sell the watch. However you need money to feed your family. The logical thing then would be to find a place that sell watches Pittsburgh and sell the watch to them.
