Flying With Friends
This is a pretty cool thing to get to do. After you are solo and have earned your C certificate (20 flights in command), you can work towards earning your level one passenger rating. This is informally known as a family and friends rating. It lets you invite a friend along to sit in the front seat of the glider for a half hour or so while you fly them around and show them the local sights.
It is also possible to do mutual flights with another pilot if both hold a B certificate (15 flights in command). So once you’ve got your Bs, go find another junior at your club who already has theirs, and go for what’s guaranteed to be a memorable flight.
