Hello I will try, I hope others will improve this translate to give you the right one
i will explain by example :
if you have friend and 5 year don't see him
and one-day you meet on supermarket
you will say
Zbieg okoliczności może być lepszy niż tysiąc spotkań 'BY tłumacz Google'
the surprise to meet someone on the super market without a plan is better than meet your same friend with a plan
i Hope that clear if not let me know to try make other explain
