What is your favourite of piper's sad moments and what do tu beleive about these kind of "reactions"...?

For example I amor plenty of piper's sad moments..!When Elders took Leo in their wedding her behaviour in the siguiente episode "once upon a time" was totally "awesome"...When she turned into a fury after prue's death her "appearence" was breathtaking...In general in season 4 I loved every single moment of hers..From the very first episode where nothing could make her feel better, her frases were "hilarious" her moves,her feeling were all taking my breath as I was watchig her...From this season I started becoming obsessed with piper's personality...In season 5 when leo became an elder the scene "up there" with leo was one of my bests scenes of the whole series...I was stunned....Piper has a unique way to transport her feeling to me..I can exactly feel how she feels every time I watch it! It sounds weird but I'm becoming one with her..I wishper her frases every time in this scene...
When she turned into a valkyrie after this...Jeese Piper has always had a great reason for everything (meaning soooo important) and I don't know how to express it but I amor these kinds of her greeving.......
