Eyes

• The colours of people's eyes and how sunlight makes them shine more!
• When people notice that my eyes dilate a lot when I'm speaking or looking at them...
• Eyelashes

Nature

• Flowers - this is so weird for me to share here but I say hi to flowers when I'm certain that there are people nearby and I say it out loud when there's really no one around...xD

People

• Who each person looks at when everyone is laughing
