Science: Human Language

Humans have many ways of beginning a conversation. I think they are a little strange... But that's humans for you!
They are:

So...
Uh...
Um...
Er...
Hm...

I feel a beat...

So, uh, um, er, hm, so, uh, um, er, hm.
Humans have a very crazy way,
of beginning something to say.
So, uh, um, er, hm, so, uh, um, er, hm.
When we don't know what to speak,
These kind of words we seek,
and they are:
So, uh, um, er, hm, so, uh, um, er, hm.
When we try to strike up a conversation,
Then with contemplation,
we think up various words to utter
so we sound like a dudder
they are:
So, uh, um, er, hm, so, uh, um, er, hm.
(fast)
We don't know what to say and that's crazy,
maybe humans are plain old lazy,
We don't know what we say but we love to chat,
Telephones, e-mail, text messages, why's that?
(normal)
So, uh, um, er, hm, so, uh, um, er, hm.
Sometimes when we don't know what to teach,
we usually start our speech
with:
So, uh, um, er, hm, so, uh, um, er, hm.
When we don't know what to say,
you should rather think about it all day
then say
So, uh, um, er, hm, so, uh, um, er, hm.
'Cause saying that does not give a good impression
When you say those words with compression
is sounds like this:
Souhumerhm!!!
So when you don't know what to blabber,
I am thinking you would rather,
Think of something better to hum,
Because when you say this you sound quite dumb,
So, uh, um, er, hm, so, uh, um, er, hm.
So what I am telling you please,
My pain it will ease,
If we do say,
What have you been doing today?
Instead of, So uh, um, er, hm
See you got it! No longer dumb!
It will make you sound brilliant!
Make you sound quite intelligent!
If you start starting to say,
Things like, 'How was your day?'
Instead of saying those things,
That most humans always sing,
So, uh, um, er, hm, so, uh, um, er, hm.
So if you follow my rule,
then you will no longer drool,
with those words that are the spit,
throw them into the pit!
And they are,
So, uh, um, er, hm, so, uh, um, er, hm. (repeat till they fade)
