Buttons and keys

We are every day pressing a button either the command, the computer keys or the mobile.
Our fingers are working and pressing many buttons every day, most using to write in social networks, play the console or play an instrument such as the piano or the clarinet.
Most people do not even know what a button really means.
A button is a round object that can be made of different materials and can have infinite colors that are sewn to the clothes and serves to fasten the garments through a buttonhole.
Most people do not even know how to sew a button to a shirt that is really easy.
