In a Conversation Relationship

They both agreed not to take it to the next level for they know what they will never be.

All they do is talk about anything that exists or that they can imagine. They send instant messages about what they’ve eaten, send emails about funny things and sometimes talk awkwardly in person about something that really doesn’t concern them.  

They often catch themselves looking at each other and just laugh it off with a big grin and send another message saying “I saw you smiling” or “I caught you looking at me and I did too”.

It gives them a funny feeling just like butterflies in their stomach. The question is, when will this end?
