The ands and buts in the usage
give a large distributive leverage.
The and is an easiest conjunction
while but is an ominous junction.
The and goes on with a free flow
directing to a temporary slow.
The but gives a break sudden
leading to a suspense in the end.
These words are a
boon to the writer
as they gives facilities to cater
with a period to think over
and a time to build over.
Without these two words
much would hold back
as great literature would pack
and go for a hiding in a set back.
