a handshake. a pat on the back. a pout. a turn-around. a simple smile. a kind look. a cup of tea. a concerned voice. a gentle brush. an accidental bump. a giggle. a snicker. an all out laugh with snorts and such. an awkward dance. a full moon. a shadow. a friendly smack. a shy burp. a sunrise. a magic leaf. a movie ticket. a slight breeze. a footprint. a spark. a secret. a tuneless song. a random sms. a strange conversation. an empty bench. an unexpected call. a beach towel. a nice meal. a quiet moment. a wrinkly grin. a dirty shoe. a sniff. a sob. a tear. an empty stare. a hypothesis. a greeting. a blank question...

"what're you thinking about?"
