Weird SMS Of The Day

Amount of short messages or calls from anonymous (or what I prefer to call -- mysterious) senders/callers keeps increasing (slowly). An interesting SMS among those can't be any other but this:

老公，回了吗？电话打不进。

English translation:

Darling (husband), are you coming back yet? I couldn't get through to you.

which I received from a Maxis mobile today at 3.55AM. I don't know whether the sender is someone I know, but I guess she (can't be he) is not.
