Regret

Regret. One most hated five letter word. Most painful one. Regret is an emotion that comes out when we realise that we have done something wrong which could have been rectified had we been a little more careful. It is synonymous with repentance. But regret is more personal. When your actions affect a stranger, you repent it whereas you regret your actions if it had hurt your loved ones.
There are so many adages such as "look before you leap" telling us to be cautious of our actions. There is a hindi couplet which goes on something like this "Ab pachtaye hoth kya, jab chidiya chug gayee keth?" meaning "what is the use of repenting when the birds have already eaten the crops?." What is done is already done. Nothing can be done with it.
So dear all, no matter how angry you get, no matter how worse the situation is, never do something stupid nor say something foolish because spilt milk and spelt words cannot be retrieved. If you do so, you will be left to regret it later.
