Does my grandpa or grandma like me?

Im 13 and when im at there house they will be sittin on the couch and want me to sit on there lap facing them and my grandma kiss's me on the lip and my grandpa got a b0ner once and it made me get one and i looked at him and he was just smiling and kissed me on the cheek. Then I will be in bed with them cause they want me in there and my grandpa will role me over on him and hug me and kiss me.
