歌曲《first of may》的歌名意思是什么？

大概表现一种淡淡的哀伤吧~~~~或者对真爱永恒的期待

附一个歌词翻译

不过翻得比较烂~~~

when i was small, christmas trees were tall.小时候，我觉得圣诞树很高

we used 2 love while others used 2 play.我们过去总是爱,其他人总是玩

don't ask me why,but time has passed us by.不要问我原因,时光已经流逝

some one else moved in from far away.有人从遥远的地方走了过来

(chorus)

now we are tall, christmas trees are small.现在我们长高了,就觉得圣诞树很矮

and u don't ask the time of day.你不问我白天的时间

but u i,our love will never die.但你和我之间的爱情永不会凋谢

but guess we'll cry come first of may.但我猜我们会在五一节哭泣

the apple tree that grew 4 u me.为了你和我种的苹果树

i watched the apples falling one by one.我看到苹果一个个掉了下来

and i recall the moment of them all.我回想起它们成长的时刻

the day i kissed ur cheek u were mine.和我吻你脸颊的那天,你是我的
