My best friend

I didn’t see the people I passed by
Because I was checking my mobile
I won’t notice what day it is
Because I’m busy watching series

I haven’t noticed the artist on stage
Because I was filming with my smartphone
I won’t notice the handsome bartender
Because I’m messaging a friend

Why would I pay attention to class
If I can google every question I have

Tomorrow I will go out for a swim
But I’m afraid I will forget my best friend
