According to Wikipedia, one of the characteristics of indexicals is that “in order to successfully interpret them the hearer must know the respective speaker, time, and place of utterance.”
Amardeep’s latest poem plays with indexicality and how it is conveyed (or not) on the web:
If you’re reading this in Delhi, Bombay, Chennai, or indeed, Taiwan, either I’m asleep right now, or you’re up very late at night, or we’re both awake, but in rather different moods. Consider the gap in time and space. How can we connect?
I’m up now, but I’m going to take a nap. Skype me.
