I have been running this through my mind since you put this thread up..
I hope I can explain it.

I may respect one's ability, because of a myriad of skills, knowledge,talents etc.. But may think that themselves as a human being is pretty dismal.

I may really like someone for their wit, intelligence and despise the way they treat others,their ethic's ...etc...

Whether I like someone or not is totally emotional I have to connect on that level.

Now to Love someone I have to connect not only emotional, but intellectually and I have to respect them. .

I do respect all beings whether it plant, animal, human, land etc.. That is just me..Now in saying that they have my respect because they are a living entity..

Now to obtain my trust and gain a deeper respect from me that takes time. When I give my respect my trust is given at the same time in degrees...When that trust is broken, I am very slow to ever give it again I wish I could say sure it will be rebuilt. But I know myself very well..

To lose the respect can happen in may ways. I think the easiest way is to deceive me or themselves.
