"rideto"?
I don't think "ridere" has got such a form for the imperative... Shouldn't be "ride"?

Anyway, since the imperative significates an order in Latin, I would propone to use subjunctive here... (conjunctivus iussivus). What do you think, Alex?

"rideto" is the future imperative.

I studied it can be used in few circumstances, i.e. when you give an order but not referred to the immediate present.

Anyway, that's a good idea.
Here the subjunctive could be more "latin"

Yes of course, future imperative! It is so rare that looks really strange to me.

But I wouldn't use the imperative here, becuase it is rather advice than an order. Isn't it?

Yes it is.

Then is this OK?
"Nunc fleas, sed postea rideas."

Yes, I think the subjunctive fits here better.

Can I ask you a bridge please, Lilly?

"Cry now, but laugh later" (In English and in Portuguese both are imperative)

Thank you, Lilly, for the precise bridge.

But do the languages (English, Portuguese) have two ways of expressing comments like Latin does? Latin has got the imperative and the iussive subjunctive. Both can convey a command, but there is a subtle difference between them in the strength of that command.
Compare, please:
Hic mane = Wait here.
Hic maneas = Wait here (meaning: You should wait here).

But, of course, we can use the imperative here too, Alex. But rather not future one. So it can be also:
"Nunc fle, sed postea ride". It can go to the remarks or just be replaced. Your choice, dear!

I would give both translations.

Would you mind to write it in the remarks, Aneta?
