So you are at the store or park, or even online somewhere.... and you spot someone you used to know. Now, they haven't seen you yet but they could any moment now. What would you do?
Walk away, turn around and dash, pretend you don't remember, or just grin and say hello? Bear in mind, saying hello might just mean you end up trading phone numbers or becoming 'friends' on social media....we all face this dilemma from time to time... what's the best way to deal with this kind of situation?
