John 2 vs1-12 Water to Wine

(John 2:1-12,New King James Version)

When we left Jesus, He was talking to Nathanael about the things he would see.

Now we are told "On the third day..." Jesus and the guys went to a wedding in Cana.

Never gave it much thought til now: third day? What does that mean?

One thing that comes to mind is that His first miracle came on the third day, and His last miracle (His resurrection) came on the third day. Probably just a coincidence. 

The wedding was probably of relative, and Mary felt bad for the cousin or whatever when the wine ran out.

We can't assume Jesus and the guys drank it all so that Mary was upset and asked Jesus to replace it. It was more likely that the newlyweds couldn't afford much to begin with.

All through this Gospel, Jesus gives replies to people that seem unkind, or uncaring, or irrelevant. "Woman, what have I to do with thee?" seems that way, but it was probably done in a laughing manner, maybe like: "What am I gonna do with you?".
What might be happening is that Mary now expects her Son to start acting like The King and supplying peoples needs, and Jesus replies kiddingly (like I said) and then tells her it is not time for Him to be That King, yet.
But mom knows He'll comply, and He does. Of course, if Jesus make wine, it's gonna be GREAT WINE.
Then He and His mom, brothers and disciples go down to Capernaum. Later, His brothers are not going to be so accepting of His calling like Joseph's brothers didn't believe Joseph.
But Joseph was his brothers' deliverer. Same with Jesus.
