Usually when I take the train, I
always try to get a single seat. I love talking, but after four hours talking
about the Palaeolithic, yesterday I actually needed a break, just reading or
listening to some music, but the train was really crowded so I had to sit next
to other woman.

When I though that I could read my
book, she touched me and said "Please, listen to me, when I was seven
years old..." then I blew up and shouted her "Get on your bike"
This week I'm going to ask you a new writing
prompt, on your bike I'm sure that
you're going to guess the meaning of this idiom.
