Why are we fighting over small and stupid things?

often when people fight over small things it's because they don't want to talk about the underlying BIG things. Maybe they don't feel valued, or supported or appreciated? If you see someone focusing on the small stuff, try asking, "what's REALLY bothering me/him/her"?

Maybe you guys are just going through something. Talk to a therapist about your problems. Talk about it with him, and see what he thinks.

Two person only can fight only if both are willing to fight if one of them don't want to fight then fights can be avoided by acting in a mature manner. Based on importance of person in your life if you keep ego away and act in a wise manner then I don't think fights can't be avoided.

Sometimes when you care about someone so much, your intentions are good but you can get so frustrated that they come out wrong and you argue because of it.

It could be stress you are both experiencing. Try talking about it with the person you are arguing with and maybe try talking to them about how you're feeling.

If you’re talking about being in a relationship then I’d say that couples arguing about little things is common. It happens to a lot of couples and can be seen as normal. HOWEVER, if you’re arguing all the time and feel miserable all the time then it’s worth having a conversation about what’s going on. Maybe theirs things that are both annoying you but you haven’t talked about. Communication is key in relationships.

Because within ourselves, we see different views. You may see something as "small" but for someone else they might see it as a big thing. It's the different perspective we have within ourselves. In an other answer, we may somehow see how it was worth. Not all small things aren't useful. They are useful too, even a glimpse of change can alter one's future. :)

We fight because of some differences we have with another person. These little things are sometimes the things that counts the most. Things aren't always as they same, one thing could be stupid for you but it could mean the world to someone else.

That's a good question; it's possible that there is a larger, underlying issue that has yet to be discussed and is showing through in superficial arguments. It is also possible that these are two different personalities clashing.

Maybe personalities clash. You might be really alike so the same things trigger arguments. You need to just try to be the bigger person and approach the situation that causes the argument in another way.
