I will consider a same day if someone contacts me before noon and wants something in the evening. It really depends upon my mood though and my availability. In order for me to function in an actual social life, I like to make plans with my friends(I am funny that way.), and set my day around noon with confirmations.

"Now" is never an option. I don't care if you happen to be in my neighborhood.
