I thought general experiences were talked about in the Imperfect.  The time markers given in this lesson match up with https://spanish.kwiziq.com/learn/theme/746448.

And also this lesson seems to indicate using the Imperfect:

Using the imperfect tense in Spanish to express habits or repeated actions in the past (El Pretérito Imperfecto)

I am curious how this structure would work if the direct object is a pronoun, something like the following.

I had a beautiful beer mug.  I accidentally dropped it.

Hola,

'Estamos a 28 de diciembre' should also be considered correct here, right?

I noticed in the given examples in the lesson for estar to talk about dates, that 'estamos a' is always followed by a date written in words. Is it acceptable to use 'estamos a' followed by a date in digits?

Thanks,

Benhur

I noticed that nunca goes after nosotros,yo,él/ella, but not estoy. Why is that

It would be great to provide the meanings of some of the expressions such as higos a brevas and se mantiene en sus trece.  Also, I would like to be able slow the speed down as they are speaking a bit fast.

In writing exercise "A perfect day in Granada", I am expected to use simple present tense to talk about the near future plans. And the "ir + verb" structure is not accepted as an alternative correct answer. Why?
