you respect other peoples opinions and decisions 

its their life 

you can give them advice and you know you should never yell at someone to get them to change because that would only make them angry and less inclined to agree with you

you have rights to say what you think 

and other people have rights to say what they think

your opinions may not be the same and thats ok

because both reasons will be different

because you both we're raised differently, experience things differently and have seen different things

different, you guys are both different

so dont expect them to agree with you
