If you could ask anyone (alive or dead, Past or Present) a question, who would you pick & what would you ask!
How can you be totally yourself? How can you free yourself emotionally and psychologicaly?
What's my fault ??
Whats the secret of peace?
@Sidwhen
The secret to peace is being able to admire the small, beautiful, good things that surround us even when you feel suffocated by issues or emotions. It's seeing a little mushroom on the side of the road and recognizing the beautifully complex conditions that allowed it to sprout there. It's being in a room and noticing someone smile to themselves and wondering what they smile about. It's sitting on the floor and feeling the room in a whole new way. Sometimes it's just being able to take a deep belly breathe. Or going to bed and knowing that no matter how tomorrow might be, you have this time of peace when you can shut off any worry.
I would ask my mom if she really believed I could make it through. 
Mom, why you go for an asshole like my father?
I would ask my dead aunt. What is on the other side?
I would ask my younger self why dont you allow yourself to love who you are?
I would ask my Grandma who died two weeks ago whether there really were no other dates for my parents wedding, because it was the only thing my mom really wanted to ask her and never did and never would but now she will never know and if I could die with nothing left hanging and no mysteries around me, someday, I would like that for myself.
I would ask my best friend Pat why he didn't come to me about his depression.
