Let’s say that yes, you pointed them to “networking”. The issue is that they have a specific problem and you are pointing to a topic so broad and deep with no specific direction. But you also say “it’s basic”. Well if it truly is basic and they still don’t get it, this would be a clear indication that they need some level of hand holding. Last if your feeling “that is a lot of work, I don’t want to do that” no problem you don’t have to. But in that that situation I would suggest reviewing before commenting: is it going to get the person closer to a solution? Is encouraging to the person? Am I indicating I also have this problem indicating someone else could step in and help multiple people at once? Is it funny? If it’s no on all those, maybe don’t comment.
