Do you typically continue to surf when you see sharks in the water with you?

Was surfing small waves in VA Beach today and saw a 5 foot and a little 2 foot shark while riding separate waves. The little shark didn't bother me much mentally but the bigger shark caused me some concern. Decided to go to shore for a bit. Wife on shore didn't believe me until I pointed them out cruising in the cuts between sandbars. She freaked but also couldn't stop watching them. They stuck around for about 8 minutes that we could see.
