Stepping back from negative beginners

Today, I had a conversation with a colleague regarding procedure for Visa appointment  and booking tickets for attending some International conference.  

And, when I said that it’s better to go for Visa first and then book tickets later upon approval. 

The first thing she said, ‘will you not apply for Visa, even if it gets rejected? ‘

{O hello, I just wanted to discuss on the way one can approach. And you are deciding onto rejection! :D} 

And after listening to her words, I quietly stepped back from discussing anything further  with her.  

A positive push is very essential, and whenever I notice people around me uttering their very first sentence with a negative notion, I just step back.
