It's Not Polite to Ask a Lady's Age

So I met this random cute girl (age unknown) at an engagement party --where I was actually not invited, but that's a whole different story--. She ran here and there looking very adorable and loveable, so I cannot help starting a conversation with her.

Me: Namanya siapa?
The cute girl: Ita.
Me: Ita umur berapa?
The cute girl: Umur baby.

Yeah, I forgot that it's not polite to ask a girl's age, and the cute girl sure knew how to answer that diplomatically, not hurting anyone but still managed to look super cute.
