Talk to your customers. They should be your best friends.
What someone needs is good human connection that is not totally associated with their project. People need friends - real friends, and it is not realistic to expect that one should seek that out from customers. Not that it's unheard of to make a real friend in that situation, and yes, the closer the relationship is the better, but let's be real. Businesses have risk. They are not a healthy place to receive all of your biological need for real connection.
Also you don't know if the poster even has customers or is even in a business where intensive customer interaction is an option.
