Today I had an interesting observation: I won't go into details and just describe what I witnessed. The woman, she is in her thirties started crying opposite me. First her mouth was contorted, her lips trembled and she was blinking very fast. She wears glasses and didn't remove them during the whole crying fit. As usual she didn't make a sound, she just stopped talking. Right before I could hear the tears in her voice. This time there were a lot of tears falling down her cheeks and at first she wiped them away with her fingers. She didn't let them flow openly but wiped them mid cheek. At one time she got one tears with her index finger and licked it off. I have never seen anybody do this. Licking tears with the tongue sticking out yes but never from the finger.
