Watching out for flirtatious behavior is a good method, but it is probably the most unreliable of all that are listed.
Is your friend exhibiting flirtatious behavior with you?
Do they find excuses to touch you, stand close, compliment you repeatedly on your appearance? Science has found that our pupils dilate when we are looking at someone or something we are attracted to.
“It is so nice to have a male/female friend who is just a friend.” “I really like this guy/girl from work, we went out last night….” “There is a new guy/girl at school who I am really interested in.

Try passing him or her something and hold it in a way that makes it difficult for them to take it without your hands touching.
When they reach to take it, observe whether or not they expend any effort to touch the smallest surface area of your hand possible.
If they move away, heed it as a warning and don’t try it again that day.
Our personal space is a personal thing and many of us become annoyed if someone we aren’t attracted to repeatedly invades it.
You can try this several times (over several days) and if he or she continues to move away as if by reflex, chances are, they are not attracted to you.
