Just make brief eye contact and give a little smile - make sure to smile with your eyes too.

If the girl smiles back, she’s likely down to chat. If she looks away or seems uncomfortable do not waste your time! Don’t take it personally and just move on.

Every woman is different. Some just want to finish their workout/study session in peace and go home to their boyfriend or s.o. Others are single and down to mingle. It’s really that simple.
