Luma has given me kisses when I ask for them since I first brought her home. I know she's angry with me if she won't do it. Then I will apologize to her and loss her forehead...and eventually she will come around and lick my hand to let me know I'm forgiven.
Luma looooves her daddy and anytime daddy allows her to kiss him on the mouth (rare. Reserved mostly for when Luma is sad/sick/clingy) she's very happy.
Rosie loves to kiss us too. We're very friendly in this household....lol.
