...Ôi cơn mưa quê hương!
Đã ru hát hồn ta thuở bé,
Đã thấm nặng lòng ta những tình yêu chớm hé.
Nghe tiếng mưa rơi trên tàu chuối, bẹ dừa,
Thấy mặt trời lên khi tạnh những cơn mưa.
Ta yêu quá như lần đầu mới biết
Ta yêu mưa như yêu gì thân thiết
Như tre, dừa, như làng xóm quê hương.
Như những con người - biết mấy yêu thương!

(Lê Anh Xuân, Nhớ mưa quê hương)
