It actually keep you out of the trouble, but not exactly solving the problem. Mouth can create so many good and bad things but even good things can be interpreted differently. So, be quiet. Thus it leave the imagination of those who actually paying attention to me, to think as they might want to, but as long as I'm not involve mouth fighting that could turn into something ugly and bad. But, it not nice actually to keep everything inside. it not good to bottle up everything because once it get out, it might turn not pretty. I guess this is also where the stress is coming from. But I belive in saying that quite is intelligent. Stay out of trouble and focus on other things.
Life is wonderful
