AIBU to pay my teenage son to practice his guitar?

[SlartyBartFast]

bought him the R**Y thing for his bday.

think he is struggling.
thought 25 a practice would be a good idea.

then of course my dd who actually practices her instrument wants now to be paid!

I used give my sister my pocket money NOt to practice her violin.

Seriuosly, don't pay him, it won't make him anymore enthusiastic, he'll pick it up of his own free will when he gets into a band he really likes.
