What is how to tell if someone has been crying?

If someone has been crying, there are several physical signs that may be noticeable, such as:

1. Red and puffy eyes
2. Tear stains on their face or cheeks
3. Swollen eyelids
4. Runny or stuffy nose
5. Hoarse or shaky voice
6. Damp hair or wet cheeks
7. Heavy breathing or sighing
8. Holding tissues or wiping their face

Additionally, the person's emotional state may also give clues that they have been crying. They may seem sad, emotional, or distant. They may also be less talkative or avoid eye contact.
