Not if you've spent your entire life putting other people's needs first it's not.
The average woman spends her life endlessly worrying about other people; her husband/partner, her kids, her employer, her parents and siblings, her friends, school network, volunteer groups and so on and so on. Even pretty confident and ballsy women get roped into a lot of shit that is essentially not their responsibility and not their problem because they are women.
Obviously being obnoxious to people close to you isn't great. But I'm going to take a wild guess that you spend a lot of time smoothing over your irritation in various situations to keep the peace on a daily basis. If you're like most women you will have gone along with things you didn't want to do, tolerated people you didn't like, given up your time for people who didn't pay for it or appreciate it, spent money doing things you're not interested in etc etc.
Has it ever crossed your mind that if you just calmly say no to people you might find you actually snap at people less? Because you've been upfront from the getgo that you don't like something, don't want to do it. Rather than doing things and seethingly silently inside. You've lost the cognitive dissonance and the deceit.
I actually find that the more direct I am with people about things I don't want to do, the less likely I am to snap. Being honest with yourself and your closest people eliminates the need to pretend all the time.
