What are deal breakers for you in a friendship? I'll go first: 1. If he/she cannot keep a secret - I mean, what's the point if I am not able to trust you? 2. Lying - Again, what's the point if you are not trusting me. Be you and be true to me. I have no business with your "facade". But, I don't usually give-up on a friendship at the first, second or third sign. Only after a few signs, I 'call it quits' and I make sure to tell them my feelings before ending it altogether. I hate it when people suddenly cut off, block or ignore the person with no apparent cause or an explanation. I believe that it is important to have a closure. How about you?
