It appears that they are now trying to catch us via text messages! I just received this:

I’m not buying it. I would suggest you don’t either. Notice they don’t mention an instrument or give you much information, and imply that they want so many lessons per week, yet only for one month? Those are most often bad signs.

If I’m wrong, he can write again with more info, but I won’t even reply to something like that, just as I don’t reply to emails that are similar.
