Well,if you're a newborn baby,then yeah,it's a positive sign.
Other than that,it's NOT something you'd want to hear from a girl you're interested in.
You shouldn't be responding to it at all,because if shouldn't have ever come up in the first place.
If a girl says this to you,then you screwed up somewhere prior.
What in the world did you say to her to get this kind of reaction anyway?
To me,this is kind of a distraction.
As long as she's telling you you're "cute" or "adorable,you can't ask her out.
It's like,"you're cute". "You're sooo adorable". Then while you're distracted by the compliment,she goes,"Ok,I gotta run. By
".
Don't be fooled by these "lines".
She's not feeling any attraction towards you unless you're being a strong,masculine man,NOT a "cute" little 5 year old.
