1. If she likes you she will smile at you "omg I was just being nice"
  2. She will laugh at every joke you say (even the bad ones). "I'm just a bubbly person, sorry"
  3. she will give the shy, coy smile."because you made me feel awkward"
  4. she will look at someone and then look away when the guy catches them "because you kept staring at me, weirdo"
  5. she will playfully punch the guy they like in the shoulder gently. "I'm just a touchy-feely person stop overthinking it"
  6. she will try to find similarities with you."Omg I'm just trying to relate to you as a person"
  7. she will often try to make small talk with the guy they like "omfg I was just being friendly"
  8. if she likes you she will not pull away from your touch "I literally freeze if a guy touches me"

The examples I listed all happened to me and there is a reason why reddit smuggies giving out advice "to learn to read the room" immediately recoil and call you "autistic" for asking them to elaborate with specifics. Turns out behavior that is flirtatious is hard to see, and there are several reason for that. Women aren't going to do it in obvious ways because they don't want to be embarrassed. Flirting looks a lot like being friendly. One woman's flirting is another ones "just friedly".
