Can you say "stalker"?

I've handed out my phone number all over Asia when random people who I've taken photos of asked for it. I don't expect anyone to actually use it (so I was very surprised when one of the little boys from my road-trek near Ooty called me at 8:30 the next morning, when I was in bed). So yesterday when I took some pics of a schoolgirl drawing a kollam outside her home, I cheerfully accepted a glass of unidentified fruit juice from her mother, and gave her brother my number. And he hasn't stopped calling since. Often I don't hear my phone ringing, so he switched to texting.

He seems to have eased off today, luckily - he's only texted five times and tried to call four times (he stopped after I sent him a message telling him I was busy).
