Yawing

Sometimes I'm sorry but sometimes
Sometimes, yes, sometimes I'm bored.
It may be because I'm an idiot;
It may be because I'm floored;

It may be because it's raining,
It may be beacause it's hot,
It may be because I have eaten
Too much, or because I have not.

But sometimes I cannot help yawning
The whole day through
And when teacher's turning her back on us,
It may be that she's yawning too.
