Don't take a book
Smile at people, keep a mental note of those that smile back
Start to say hello
Comment on children or ask advice about a particular problem (Potty training / weaning / behaviour)
Have a laugh, and be natural
Do it over a period of time (weeks ie first week smile and say HI, next week say Hi to same person, ask how they are / comment on their kids), not all at once or you'll look desperate
....
I am probably overly socially confident and make friends quite easily TBH but it comes from having no barriers (I'll talk about anything and everything to anyone .. but judge the kind of thing they'll talk about first).. its amazing how many people love the opportunity to talk about themselves
I wouldn't approach anyone obviously reading a book because I would think that they're taking a well-deserved moment to themselves
I will smile at anyone but after a few weeks of just smiling without having started a conversation I will probably just keep smiling but not consider that person a potential friend
Its being able to create openings for conversation
And some people do have too many people in their life and can't find time for new 'best friends'
sorry I rambled but I get really upset when I read posts like this and realise how many people feel uncomforatble at these M&T places which are supposed to be our lifeline .. I just want to take you under my wing
