My mom doesnt understand the term "unconditional love..." what is wrong with her?! please help me here....?

not much else to ad. i believe in unconditional love...its the only way to go. a parent SHOULD have it engrained in their psyche....their being....to love without strings attached...unconditionally. you shouldnt love someone then set limits...or conditions on that love. for example...ill only love you if you clean your room, or come in before curfew...or, ill only love you IF you LOVE ME. that is wrong, and selfish, and NOT EVOLVING. am i right?thanks
