Expect what you want

There is something I've come to realize and that is that the way you act and feel about and with other people will have a great effect on how they act and feel toward you. Other people become what you expect them to be.

Expectations
If you expect them to be mean to you, be impersonal, ignore you etc. then you will yourself act in various ways to either counter what bad will come by protecting yourself or avoiding that person all together.

Now if you instead expected that person to be kind and open toward you then you instead would be letting your walls down and meeting that person on the same level.
