Arms linked in friendship

One thing I have observed in this past year that is quite an endearing thing. We see women of all ages, and mixed ages, walking along with arms linked in friendship, visiting as they go. The comment was made that the older women may do it as a support as they walk on the uneven sidewalks and cobblestone streets here. We see teenagers, young women with mother or grandmother, and older women and it's a very friendly, warm thing to witness. It's especially a contrast to the somber people who walk along, looking ahead, not seeming to be aware that anyone else is around.
