Prosím, může mi někdo vysvětlit, kdy mám správně použít „I“ a kdy „me“? Např. ve vazbách „Já a moji přátelé“, „Moji přátelé a já“.
A pak bych se chtěla zeptat na rozdíl mezi „between“ a „among“? Děkuju!

I je podmětový pád následovaný slovesem, např. „Moji přátelé a já tam jdeme.“ – “My friends and I are going there.”
Me je pád předmětový („já“ bez slovesa) (mě, mi, mně, mnou), např. „Oni tam jdou se mnou.“ – “They’re going there with me.”
between mezi (dvěma)
among mezi (více než dvěma)

Among expresses a relationship when more than two persons or things are involved: Distrust spread among even his strongest supporters.

Between is used when only two persons or things are involved: between you and me; to decide between tea and coffee. Between also continues to be used, as it has been throughout its entire history, to express a relationship of persons or things considered individually, no matter how many: Tossing up coins between three people always takes a little working out. Between holding public office, teaching, and writing, she has little free time.

Between is used when the entities are considered as distinct individuals; among, when they are considered as a mass or collectivity

The bomb landed between the houses, the houses are seen as points that define the boundaries of the area of impact (so that we presume that none of the individual houses was hit). In The bomb landed among the houses, the area of impact is considered to be the general location of the houses, taken
together (in which case it is left open whether any houses were hit). By the same token, we may speak of a series of wars between the Greek cities, which suggests that each city was an independent participant in the hostilities, or of a series of wars among the Greek cities, which allows for the possibility that the participants were shifting alliances of cities.
For this reason, among is used to indicate inclusion in a group: She is among the best of our young sculptors. There is a spy among you. Use between when the entities are seen as determining the limits or endpoints of a range: They searched the area between the river, the farmhouse, and the woods. The truck driver had obviously been drinking between stops.
