This is why I don't

It had been a while since my phone was last charged. From a number I didn't recognise, a message obviously not for me:

"i miss u"

So I composed a message back. It took ages, even with making a concession to the medium of using the word 'text' as a verb (it felt wrong but I thought it might be more easily understood).

"Sorry, you texted the wrong number."

In reply, seconds later.

"fuck u"

There's only so much you can do. I consider the correspondence closed.
