Who are the Fixies

What fixies
Small in stature!
We need them through glasses
It's not easy to see.
They're such a small thing,
That there are almost none
And who are fixies –
A big, big secret!
They fix it from the inside
Irons, motors,
Phones, MP3,
Other devices.
The clock doesn't run without them,
No light shines without them.
And who are fixies –
A big, big secret!
I've seen them recently
, but I haven't caught them just a little,
Only Dad said to me,
"Come on, it seemed like it."
It is impossible to catch them
, It is impossible to get on the trail.
And who are fixies –
A big, big secret!
They have a conditional sign –
I found out by accident –
You need to do this with your fingers.
Only this is a mystery.
They tell you
Your fervent greetings,
But who are fixies –
A big, big secret!
