what will you do when your friends have different thoughts or opinions with you

I try to accept it calmly. However, it isn't easy, especially when I am sure that my opinion is true and her is wrong.

    For one thing,  I wouldn't have a cow about it.

[for student's of English,  giving birth to "cow" would be a  very stressful experience for a human being.

Thus,  referring to Having---A--Cow  indicates, as an idiomatic  expression, the idea that

we become stressed out or extremely upset about something common or ordinary in human experience.

The TV cartoon character,   Bart Simpson, is depicted as saying;  "Don't have a Cow, man!"]

     People are entitled to their thoughts.  Besides,  some criticisms of our persons is a beneficial opportunity for us to examine ourselves.  Sometimes,  criticism from others is simply negative behavior.

We can regard gossip as the endless clucking and squawking of Chickens.

     At the same, we can recognize that one of the endless problems with mankind, is the negative habit of launching   ACCUSATIONS against other people. This creates massive problems.

  For example,  in English speaking countries, there are  occasions when people begin speaking with the following phrase:

   "You know what your problem is?  Your problem is  _________________?_________."

   It may be reasonably concluded, we all have a "problem". 

 It is unfortunate, that some  people suppose that being "honest" is fault-finding with others.

   I think that we operate with much wisdom, when our honest communications with others is an

acknowledgement of the basic Good that  can be found within others.

Ok everybody have his own opinion .If there thought  is good for man kind i should flow there thought.

It depends on the situation. If we talk about your own case, only your situation, which is relevant to you. In each of them, I just take note. Any way, everyone have to make his own decision. But it has a different meaning if we are dealing with a different situation, when you need to find a general solution with your friend or your close. I usually face this problem when I travel with my close friend. Her opinion is always important to me. In any situation we together try to find a compromise.

Let them.
