I think back to my first handful of 'landings' in my trailer and how I worried a wee bit about making all the hookups and even about backing the trailer into the site.
People at the parks tend to watch everyone else back in. It only took me a time or two to realize what you just said, that they tend to watch with a genuine helpful and friendly nature not because they are trying to make someone nervous. I learned a LOT from the folks who parked next to me years back. I was always a little surprised at how they would point out litle things to me without smiling or making a big fuss out of it.
Kinda like this forum here.
