I could not stop myself, excuse me and my sens of humor!
refering to your question....knowing that olas means waves...I would tell you that there are waves everywhere in DR!
Your question is ''Como es las olas?''.....debe estar ''Como son las olas'' because it's plural! And then you can answer with your nickname which is FRIO..... It happens sometime that the waves are cold!
Never mine, I'm crasy!!!
Have a good day and I hope you'll get a serious answer soon!
