"There is only power, and those too weak to seek it." 

We are;
ambitious, cunning, determined, ruthless, realistic, self reliant, charming , bold, prepared, subtle, assertive, and know how to use intelligence as a helpful tool to achieve such goals. 

We are not disloyal, but we are highly selective of our loyalties towards different people. 

We thrive for positive attention. 

We care of impressions we have Towards other people.  

We are enduring and strong. 

The bad stereotypes are nothing to us. We continue to be those cunning folks that do anything to achieve goals. 

You'll make your real friends in the House of Slytherin.
