Yea, i am :lol: i don't have grandads but i have a nan that we go up to see every so often to stay, and i get shy around her, i get uncomfortable when i'm in a room with her on my own, coz i know i would have to say something to avoid an ackward silence. But then i don't really know what to say to her and she's quite an outgoing loud nan lol. So i just talk to her when she asks me something, and i keep the answer short
And i have a Gran, but she's deaf, so it would be a waste of breath having a conversation with her coz she can't hear and me having to repeat things over and over, which isn't going to be good for me, coz i'd get all tongue-tied.
I also get shy round my Uncle's and Aunties too, and coz i don't see them very often.
