Today's Ignorance

Whenever I bring my laptop to Starbucks,
I'm always afraid it might tip backward,
so I keep it close just to be safe,
which leaves me with very little space to take notes in front of me.
But I just looked at the table next to me,
and they had pulled the chair on the opposite side closer to the table,
using the backrest as a support,
to push the laptop further away
and create more space.
My ignorance has been exposed once again today.
