Why are we fighting over small and stupid things?

There are so many reasons why people fight over trivial things. I've found that usually when something else is going negatively in a person's life, they tend to take it out in other ways. They displace their emotions. Sometimes dealing with that particular situation becomes too difficult or frustrating and the way to vent would be to argue over things that don't matter whatsoever. On the other end of the spectrum, maybe there was just some miscommunication taking place. Either way, communication is always key in order to figure out what is wrong (what the problem/issue is) and how best to fix it!

because we care for each other and our heart is sensitive to the behaviours of those who we love since we have given them the power to hurt us

You fight over the small things because you never expressed how you felt, so you pent up anger or irritation on the small things. And then you explode.

because those "small and stupid things" could mean a lot to one person but mean something completely different to another person.

Because we often fight to be RIGHT, but in truth, there is really no right and wrong. So we are causing suffering on ourselves fighting over small and stupid things. However, there is really no small and stupid things as well. Everything is based on perspective. ;)

Many people expect perfection. The world is not perfect. We must understand that. If you feel that things aren't going as you want it to be, it us best to talk to someone about it.

Sometimes the small and stupid things aren't as small or stupid to the other party. Other times there are underlying issues being triggered by the smaller arguments.

Patience and taking time time to understand each other may be all that you need. Disagreements are bound to happen and as a matter of fact, if handled well, it makes you to know more about yourselves. Disagreements occur between siblings as well not to talk of if you are from different backgrounds or homes. But the key is asking yourselves, "do you want this to work?" Then you have to learn how to sit together and talk issues out so "this" can really work. Thank you.

Because these small stupid things don t always appear to us as small and stupid and for the most part they re a result of something thats been building up in our mind for so long..and that small stupid thing is only the needle that pops the balloon.

Sounds like you are both under stress and outside pressures. Communication is key. That and a good nights rest.
