Texts seem to have different rules from emails for some reason. Many people seem much more likely to use them in a back and forth conversational way. Maybe it's to do with getting and sending them on the hoof rather than when specifically using a computer.

I believe people who get and receive their emails through mobiles use them more that way too. Perhaps the lady has a Blackberry, and that is what is happening.

I can't see why it makes much difference whether the lady in question fancies P-Vine rather than just likes her. The issue is surely whether the is attention is experiences as excessive rather than what motivates it.
