It is bad enough to cry over spilt milk. But many of us do worse; we cry over milk that we think is going to be spilt. In line 1 sic=such; 2, a'=all; 3, nae=no; 4, enow=enough; 5, hae=have; sturt=fret, trouble.

But human bodies are sic fools,
For a' their colleges an' schools,
That when nae real ills perplex them,
They mak enow themsels to vex them;
An' ay the less they hae to sturt them,
In like proportion less will hurt them.

Robert Burns
