email flows and decision

I've just invited a friend to spend the week end in London. Looking back at my emails, I notice it's taken 10 email correspondences (five emails each) to invite her.

Any simple decision involves a surprising amount of email exchanges (my average is 10-12) be it deciding where to go for dinner. No time to think about the sociological reasons for such reasons but I believe (from personal experience) that email, in the workplace at least, are a sort of entertainment, a mini-break from your activities -and thus the more emails you exchange (saying nothing), the better you may feel.
