What kind of person am I, to not need cell phones in our period? I must acknowledge that it is very handy in case I'm late. Certainly if the person who is waiting for me has a cell phone, I can inform them on the way from a public booth.
On the other hand, when that person is late, they have no way to contact me. Which allows me, who cannot wait for more than fifteen minutes, to peacefully go home immediately.
Anyway, it's the late person who's bothered the most.
Which would mean that people like me who don't own cell phones are selfish. I hope you're not angry at me, right?
