Communication is so key in many aspects of life. Be it with your partner, a family member, or the cashier over the till. There's a saying that goes, closed mouths don't get fed which falls under the umbrella of communication. I wasn't much of a talker when I was younger because for one, I was a shy girl who preferred not to attract attention (I'm still not big on attention but when necessary, it's welcomed and appreciated). Without communication, people are left confused, unsure and upset. In order for this not to occur, we all have to make an effort to talk to one another.
You might find this silly, but way back in the day if someone upset me or made me angry, I wouldn't want to bring the matter to their attention, in order not to upset THEM.
Of course as I grew up, I realised that I had to stand up for myself and let my voice be heard. Now I don't hesitate in letting the important people know the good, the bad and the ugly. If someone does something you particularly don't like, you need to voice that hurt. Not only is it freeing, but if you keep it in, nothing will ever change and you will remain upset with only yourself to blame. It's also quite unfair to give the people (that matter to us) the silent treatment. It is immature, it is petty and we probably wouldn't like it if it was done to us. It's best to let your voice be heard so you can move forward with clarity.
I'll be the first to say that I am not a big fan of confrontation, however confrontation involves communication. If you're like me in that respect, I say find your confidence. Don't be like the Nengi of way back in the day, be like the Nengi of now who speaks to be heard. It can be daunting at times, but I believe that we're all confident individuals, some people just have to dig deeper than others to find it. Communication isn't only 'key' in the situations explained above, but also because life moves very fast. So never give up the opportunity to tell your loved ones how much they mean to you. Let us all speak to be heard.
P.S There are situations in which communication isn't necessary and only YOU know what those situations are. Yes, it's good to be polite and let people know things, but sometimes an explanation isn't needed especially when your decision is in your best interest. Ultimately, we will always know what deserves our communication and what doesn't.
