TXT mystery

I have just received the following text message from a person unknown:

Boy, BOY, i know you're awake boy

This happens every six months or so. I get sent a text message or even a voicemail from some girl who seems to have a rather volatile relationship with her boyfriend. I only ever get the merest hint of what's going on but the messages I get are invariably something like "Stop avoiding me. If you want to talk, come round later, I'll be awake". She once left a voice mail that I mistook for an old friend of mine so I hit the 'recall' button and started talking to her. It soon became apparent that neither of us knew who the other was. She hung up quickly, probably embarassed for having left a fairly intimate voicemail at the wrong number.

Occasionally, though, she makes the same mistake and I get a text message. I don't reply - wouldn't want to embarass the poor girl any further.

Having meandered off on that little tangent, I don't think this message was from her. I sent a reply saying "I am awake. Dunno' who you are so you have me at a disadvantage".

It'll be interesting to see if anything comes back.

UPDATE: Just received a reply. "Maybe I like taking advantage boy". And another! "Come on I know you are a toilet trader".

Hmm. Should I reply? Could be a nutter. On the other hand, there may be a story here.

FURTHER UPDATE: Mystery solved. Just an old friend messing around. By some bizarre coincidence, it is the same friend that I mistook that strange voicemail girl for I mentioned above. Small world.
