For me, I would say it depends! If I was on a mission to catch large Carp from a big low stocked water, then I would be alone, I fished this way for a 10 day sesh and spoke to only one person in that time. Many of you will not understand this hermitry, but I can say that after a few days alone, you become one with the water and your quarry! So much so, that you can feel the change in air pressure, you pick up on every detail around you and just know when a wind is going to grow and push into your baited Bay!
On the split side, on easier waters I'm up for a social fish with a couple of good friends, a beer or ten and a BBQ, these days I do more of the latter due to my location and the logistics!
At the end of the day, go and enjoy your time on the bank, no matter if the fish get involved or not!
