Mind you, there is nothing inappropriate and no issue intentions within this question.
^^ VERY good picture to express ourselves, lol.
Anyway, no. And I do hope you mean kisses on the cheeck. My sister, which is one year older than me, never gives me kisses (I'm not sure if she did when I was young, for some reason i can't remember my childhood completely). Now a days, she barely shows any love to any of us (in the family). To tell ya the truth I'm the one giving everyone a hug out of random... but uh, yeah, that's another story!
Nah. You two are probably somewhat dissconnected with each other to the point that hugs/kisses are not felt to give from the heart, y'know? Like I said, my sister doesn't give hugs/kisses to anyone in our family (4peeps), but that doesn't mean she hates us. You know that by seeing how she reacts with you. Just observe how she interacts with you. I think you know when someone dislikes/likes you, no?
