Do you regret being emotional sometimes?

There are certain situations we act on our emotions,its hard to convince ourselves at that time but at later point of life we think I wish I had stopped myself from being emotional and just be firm,even if it hurted that time but later on it would be a good decision.Just wondering things would be different we don't always act on our emotions.It doesn't make us less as human.Elders always say be emotional when necessary.Its just purely wisdom to know when its necessary and when its not.We can't take all our decisions of our lives trusting on our emotions even if they are major ingredient which make us feel human.
