Confused..

A person asked for water.. I said "I will bring it." The person asked me "you have cold water???" I said "no as we don't drink cold water. I'll bring you normal water to drink". The person said "then I don't want water."

Now I'm confused as to you want water to quench your thirst.. Why be so particular on cold water? If there was an option of choosing between cold water and normal water and you choose cold water then it's fine. When there is only one option you won't even pick it up for an essential need??? I would even accept this for matters which can wait but thirst too???

I'm only left thinking how this person would decide on crucial matters in life??? Is a personal choice that very important than a basic need??? What kind of a mental state he or she would be? How would they look at others needs/preferences?

I can be easily told off "my choice my life" but still I'm pissed off..
