Morning sumi! I've seen this quote before and I always wonder about this part, "...silence will always be the best revenge...". Maybe I'm not reading it the way it's meant but it always makes me think of the dreaded silent treatment some people employ. I'd much rather have someone tell me what I did that's bothering them, than get no feedback at all. The ex was a master at the silent treatment, he would go for days without saying what was bothering him. Of course, now I don't hear from him at all so the silence is a blessing, lol.
Probably reading too much into it, just thinking out loud (always a dangerous thing to do, especially early in the day).
