minimum of one second per person (of course assuming they do not break the eye contact
first). A common objection to this is "but if I keep eye contact for X
seconds" it will seem creepy. This is an excuse created by your fears.
Remember that if you keep eye contact for any amount of time, they keep eye
contact for the same amount of time. Shy or anxious people often
forget this, and it comes across as nervous and insecure at best. Shifty and
unreliable at worst. Do, of course, pay attention to the situation - do not force an
eye contact with someone who seems angry or afraid, or who scare you. There's
no need to antagonize people. But be aware of when you have a real reason to
think you need to break eye contact and when it is driven by your anxieties.
