Is saying hi mean

Sometimes it depends on whether you are a male or female, boy or girl, man or woman, child or an elderly person and where you happen to be at that moment.

If you are a pretty girl maybe he wants something more intimate with you.

If you are an elderly person or the only other person present maybe he wants to be polite.

He may be a nice, friendly guy and you shouldn't look for any other hidden meaning. Drama isn't always present. Sometimes hi just means means hello.

These signals of human relationships vary widely.
