i totally agree with all thats been said. All gliders are different and some like human company more than others do.
I have one, Onion and a sadly departed Holly, who prefer human company to gliders, to the point where as soon as i entered the room they would be waiting at the door and jump straight on me.
Another one (Biscuit) is tame, but in his own way. He doesnt like affection and will only settle for a quick stroke on the head, but hates anything cuddly.
Another (Widget) is a bit tamer then Biscuit but still, it has to be on his terms, unless you get him when he is sleepy and then he will be lovely, but as soon as he is fully awake he will want to be with the others.
And Gizmo is very affectionate but more cos he is scared of everything outside the cage and feels more secure with me more then he really wants to be loving. That and he is an attention seeker, barking at about 4am to get a kiss on the head and thats his sorted! lol
So as you can see, each glider is totally different!
