[hola]

there is an ongoing debate as to how to correctly say you can be polite when you want to

at first i thought it was puedes ser cortes cuando quieres
then i found out it was puede estas cortes cuando quieres

another spanish expert actually told me both were right
i know he has to be wrong even though he is an expert

i can understand why one would think it's written w/ ser
i can also understand why one would think it's written w/ esta

the spanish word for be or to be is ser
