I'll be the first to admit that I'm absolutely horrendous at reading signals. Few days ago I went out with a friend who we have quite a number of mutual friends between us. End of the day she invited me back to her place to smoke weed and we both ended up smoking on her bed. She was nice and all but she did not show any signs of interest (that I was aware of). Could this be strictly platonic or is she just waiting for me to make a move?
