Our grandparents could send postcards when they went on holiday.
We could send letters when we were little.
My grandma could call her friends from home.
We couldn't log in.
They couldn't read their text messages because they were in a no WI-FI zone.
We couldn't use the PS4 because there was no electricity.
They couldn't use their mobile phone.
I couldn't call you because I had no signal.
