How would you react if an unkown number (with no profile picture) send you a message in whatsapp?

And claims to be a certain cute girl from college you have seen in quite a few lectures asking you if you're about to graduate soon? How would you react and why? (If it matters, she got your number through a common whatsapp group of a big course at college you both attended).

Ignore or even block
