As a human it is normal for you to get annoyed sometimes. Yes! but you shouldn't be irritable (don't be easily annoyed or angered). For instance, if someone says are you stupid? to your own self or someone else around you. You don't have to be annoyed. Because, that is just a question and which you are expected to respond Yes or No or better still keep quiet alternatively. But most times, when such statement is made, many people often misconcept or mistake it to be an insult. Anyway, take note of that. And mind you, irritability is uncalled for and often catastrophic. In fact, excessive anger or irritability can cost you your own life. Thus, desist from it (irritability). I mean, don't be tetchy i.e. don't be easily annoyed or irritated, come what may (no matter what happens). ~Emeasoba George.
