I am thinking of going out of home without a cellphone, for one day.

For one day. HA! That sounds liberating, though. I hope you do it.

I do that almost every day of my life.

Remind you of a simplier time. Its prolly a good idea just to be more in touch with reality? Maybe map out where there are pay phones in the eventvu actually do need to call someone.
I think this scenario will be a reality show someday.

It's fun, try it.

Try it, it's nice

Map out internet cafes?

With pay phones around.

You might need it.

You rebel you!!! 😱😱😱

Why?

I've done it but left in my car turned off in case emergency
