Honestly.

You might really want to consider not taking advantage of my patience. Every one has their limits and that includes, me. :) And I have been very patient for a long time. Plus, you really don't want to see me lose my patience. I'm pretty sure you won't like what I'll be and how I treat you then. I don't know how long will my patience last. But I'll try my best to not lose it. And I'm sure you don't like it when people tend to test your patience. So yea, think about it.
