• "i thought about you" gifts — rocks, trinkets, small items
• anxious leg shaking and fidgeting
• carrying pain meds just in case someone has a headache
• collecting items (cards, shells, etc)
• drawing on hands
• falling asleep on someone's shoulder
• filler words — "um", "and", "like", "uh"
• focusing so hard you can't hear yourself getting called on
• hand gestures when talking about something passionate
• holding an umbrella for someone
• leaning into your notebook when furiously taking notes
• pushing hair out of someone else's face
• resting your head in your hand(s)
• scribbled, rushed handwriting
• sharing music tastes and making playlists together
• subconscious head nodding when another person is speaking
• swaying back and forth while waiting in line
• talking about interests
• the "aww" sound people make when they see cute animals
• tying someone else's shoes
• waiting for someone else to tie their shoes
• waking up in class and having red print marks where your head rested on your hand
