Yes... Don't start off with separating a bonded pair... But that is not to say that months down the road after they are well and truly bonded to you, and you have more than two, you can't take someone out and just have one on one time with them. Luna is my major cuddle bug. She will jump out of the pouch in the middle of the day and be waiting at the door of the cage for me. I will let her out and she will dive down my shirt and curl up on my chest, sticking her head out of my neckline to watch me with the softest expression in her eyes while I rub her head. She will actually fuss at the others if they try to follow her. She does seem to really enjoy having me to herself at certain times, and I don't think that's me projecting onto her, either.
But, she is a special one and not like a lot of gliders. I'm blessed in that both her and LittleBit are very bonded to me... My other three, although incredibly sweet and showing a lot of potential to also follow in the other two's steps, are still a little bit more independent... I would never leave any of them behind in the cage alone. It stresses them out.
