asi.

it might work...always depending on entonation or in corporal expression

Esto es lo que dicen los profesores a un alumno cuando algo no iba bien (el alumno había hecho algo malo o se había portado mal, etc.)
También se puede usar "patio" en vez de "recreo", pero creo que el uso de "recreo" es más extendido.

Hi again Sam,

I'll restrict this to what one might say in Spain - each Spanish speaking country has its own particular expressions.

As with the other question, yes there are equivalents, but no, they are not always directly transferable to adulthood.

Te espero a la salida/ a la salida te espero is commonly used, although more often between classmates arranging for a playground scrap.

The concept of "ajustar cuentas" (set the record straight) is more teacherly, as is "de ti me ocupo más tarde" (I'll see to you later).

The added value to these expressions using them as an adult is that there is no reference to break, playground or lessons - you could use them in almost any context. Apart from 'menacingly', they can also be used when flirting or with a certain naughtiness you might want to use with someone you want to 'see' in a different way, if the adequate tone of voice is used.

Anyhow, that's my tuppence.

Good luck!

Álvaro :O) :O)
