That's a great experience and memory. Small gestures like this one create strong positive attitude!
Perhaps it is your good soul and aura attracting good people? :)
Some say we are just clouds of particles and everything is energy so it would make some sense we attract the same matter we are built of :)

That was probably too abstract but I have definitely noticed how good things happen to me when I am in a good mood and vice versa :)

I don't recall having any troubles any of the times I traveled to Serbia. Apart from crossing that border with Hungary but then, it wasn't the Serbians but the Hungarian border policemen :)))

Thank you and you too have a great week!
