Yes, I had many encounters with 'gypsies'. Much more than the average. I had two close friends in Ireland who were Travellers and this is what I found.
They have an abiding distrust of outsiders, many of who shun them, and many of whom are shunned. Some of this behavior is deserved on both parties, but as Leo has pointed out this is typical of elements that make up a minority group.I treated these people honestly and did not sneer at them, or fear them. They quickly got used to my manner and I was invited to caravans to eat with a number of families, an unheard of occurrence. They became fiercely loyal to me and I reciprocated, and this over many, many years. I still keep in touch with my friends despite the distance. We have been friends over twenty years.
On one occasion one of the younger travellers stole something from me. Two days later his father appeared with the item in his hand and returned it. The youth was made to apologize in front of his family.
I always think it more honorable to understand than not to. I like these people, there is not a petty one among them and they have hearts bigger than one might hope for. Rough diamonds? Sure they are, but they have their own standards that are historically inherited.
