Jubilant, adjective: showing great joy, satisfaction, or triumph; rejoicing; exultant.
In our part of the world, we have just two main seasons – Summer and rainy season. The rains usually stop by October every year. Then they start only in June. By that time the weather is very hot and everyone waits for the rains. The first rains bring great relief and joy. I always feel the trees and plants rejoice when they get water from above, it is as if the leaves are dancing with joy. Even if we water the plants, water from above is something altogether different. There is a feeling of jubilance everywhere.
