Um,you are asking 2 separate questions,aren't you,Troy?
I think having an open mind in a relationship is when the two people can say anything to each other,mainly sexually.
And sometimes the reason people talk and never really listen to what they say is because they are in an insane asylum and they have lost thier mind.
LOL...just kiddin'!
It is because alot of people do not practise what they preach.Alot of people would rather talk about you,and they don't look in thier own back yard.Some people think they know it all,and have done it all.And there are those who just plain do not care.It is always easier said than done.
