Why do you have to include the word 'all' for 2p plurals? Unnecessary and inconsistent!
In the initial placement, all of the "you" statements were implied to be plural and wouldn't accept a singular despite no indication of it being plural
You do not, this was an oversight in the first version. These have been fixed, but it will take days for all changes to take effect.
Is the speaker combining librum and amatis and saying "mamatis"? Is it just me?
