Guys, if a girl were to say, "We should talk sometime," what would you suspect?

Anonymous
I've had an interest in a guy at the library for a little while now. I feel like he might be interested, too, as we've locked eyes twice and he always smiles whenever we spot each other.
The other day I took an item to the front desk (this was our first real chit-chat we've had with each other). He checked it out and said, "I just watched this last week. It was my second time. Have you seen it before?"
I told him no. He said, "It's really good."
I said, "We should talk about it sometime."
He smiled and said, "Yeah we should."

Would that be perceived as flirting or just friendliness? :/

Also, when the guy said that to me, would that indicate he is interested?
