Sensitive or manipulative?

Gavin is staying with my mom and dad and sister for a couple days. I miss him but it's nice having only one monster around. My sister called and said he talked her into letting him sleep in her bed with her! (Keeping in mind that my sister has a twin bed in her room in addition to her queen bed which would be where he sleeps when he stays there.) Anyway, she said he told her he gets "lonely in his heart" when he sleeps alone! And, of course, being the Aunnie that she is, she couldn't let him be lonely so he got to sleep in her bed...sucker!!!
