I honestly don't expect people to be "fair" when it comes to preferences. People like what they like and want what they want!
Thing is...
People just need to understand that just like they may have specific preferences or archetypes, so do other people. So, in that sense, it would be in their best interest to be fair at least for their own sake.
I have learned that the greater the expectation or the more stringent their preferences, the greater the disappointment.
Usually, has people get older, their preferences/expectations may either change or they may tone down on said preferences/expectations.
Perhaps, life experiences may humble people where they may not have a choice but make adjustments or they may meet people outside their preferences/expectations which may change their mind..
I just hope that people will do them and for those who may not meet whatever criteria they may possess, to respect their choices, space, peace, etc. just like they would want the same people to do for them..
