What do children do when parents quarrel?

Every loving couple would have diferences in opinion and occasionally this could lead to heated arguments and quarrels. This is something that you never tell anyone else except close friends. What I've learnt over the past few days is that adults never seem to bother much about what happens to their children when they are busy feeling hurt and hurting your spouse. Sometimes, we 'quarrel' in a nice way where it is done away from the children but Clarissa reads body language very well and would often ask, "Why, Daddy?".

What do children do?
1. They feel fearful at the next thing which could happen.
2. They wonder how come adults also behave like kids
3. They are confused as adults are supposed to be composed
4. They make sure their mischief doesn't cause further trouble
5. They occasionally get involved with the person whom they emphatise with (through their gut feeling)

What do adults do?
1. They feel the hurt longer and insist on protecting their 'rights'
2. They wonder what happened to the person whom they married
3. They start to believe what was advised by their friends and parents against the marriage previously (if any). Their worst fears have unfolded and become true?
4. They forget that their spouse was never perfect in the first place
5. They compare the good that they have done and the bad that they had received
6. They forget that the children are around and start to behave like kids too

Parenting is not easy but staying together as parents may also pose as a challenge.
