It can be seen from a distance that a small child is picking vegetables from me

Three small children are working in the field. I think they are collecting hay for cattle. Or collecting vegetables to cook curry for eating. I don't understand exactly what they are doing in the field. But as they were returning from the field I asked them and I wanted to see what they had collected. Then they showed me they were collecting grass from the field. They have pets in their house. As there is Khasi, they are collecting grass for that Khasi and taking it away. I thought something else.
