<human>: Summarize the given text in a few sentences.

A family friend passed over my email to a guy she knows that lives across the state from me. TBH I told her (and him) right away that I thought our age difference too much. They both insisted on giving it a chance and so we had two or three phone calls. Suddenly, BAM the guy announces he is flying to see family in canada and is flying through my city (two day layover). He plans a late lunch for us on the day he lands and planned a breakfast or lunch the next day. Now, here's my dilemma: I have zero feelings for this guy. I full on plan on having ONE lunch with this guy and then telling him at the end of the date that I just don't feel like things will progress. My brother thinks I shouldn't even go to the lunch but I feel bad that he came all this way, flying through my city specifically to see me, and not at least giving him some time. At the same time, I'm probably going to give him hope. 

So what do I do?
<bot>: Not interested in a guy but have a "date" Sunday that is flying across the state to see me. Cancel before or go and break it to him at the end?
