4. We notice that subtle change in your tone.
If you normally end each text message with an exclamation point and lately you've been using a period, you better believe we'll pick up on it. Highly sensitive people are generally more intuitive when it comes to the tiny nuances of our environment and we're more affected by shifts in other people's moods.
5. We're always willing to hear you vent.
Don't be afraid to reach out to use us when you need a shoulder to lean on. Our overly-empathetic nature allows us to be excellent listeners when you need it, because when you feel pain so do we -- and we want to do whatever we can to make you feel comfortable. Highly sensitive people make excellent teachers, therapists and managers for this reason.
