Lucky you, cath! That was so kind of them!
Are they nanking cherries?
When I was growing up, we had bushes of them at home and my mom made the best jelly from them.
When we first moved here where we are now, we had one bush, and our neighbour would let us pick hers, too, and I made the jelly too, it was awesome! However, they've all died...
