I'm using a throwaway account for obvious reasons but I ran into an old female acquaintance of mine who was with here friend (male, but irrelevant (?)). I'm slightly interested so I made sure to do the smiling and tried eye contact, until she just did not, and would not break.

After about 15 seconds of straight eye contact it's too much, and I'd break. So seddit, what are some tips and tricks you know of to help make and keep eye contact.
