what u think, what did Dumbledore see in the Mirror of Erised?

I think he saw his family alive. The mirror is supposed to onyesha the biggest desire wewe have: surely he'd wish his sister was alive zaidi than her still being dead, but him not being the killer?
Also, I figured the whole point of him wanting the Resurrection Stone was so he could bring his family back to life, which means he clearly desired it very much. Otherwise taking such a risk would've been foolish, and Dumbledore wasn't a foolish man.

his family ;)

I also think that he saw his family alive and I think that's Dumbledore's greatest desire. I don't think that his greatest desire is to see that he wasn't the one who killed Arianna, because well, even if he didn't, he'd still be pretty sad she's dead, no? So, why not just desire her being alive, rather than wishing he wasn't the one who killed her? O_O Does that make sense?

He saw his sister Ariana happy with his father and mother and of course Aberforth DER!!!!!!

Ariana definatly.

Ariana... no doubt

His family...not "a pair of thick, woolen socks."

I think he saw his family, just like Harry saw his own. He long desired to see his sister, father and mother alive. This is why he wanted the resurrection stone. Later he found one of Voldemort's horcruxes which was Marvolo Gaunt's ring, and he knew it was cursed. Then he found out that the ring was the resurrection stone. He longed to see his family so much that he was tempted to where the ring/resurrection stone, even though it was cursed/poisoned. The curse blackened Albus' hand and made it useless, Professor Severus Snape stopped the curse from spreading across his whole body. Later in heaven Albus Dumbledore looked back on this and called himself a fool for wearing the ring, temptation got the better of him. From this information one can only conclude that his utmost desire was his family.
