a cake but I didn't

I was going to make a cake but I didn't.

but I didn't

but I didn't*

Zawsze uzywaj be going to jak miales zamiar cos zrobic. wzor: I was going to.. , but I didn't You were going to..., but you didn't He/She/ It was going to ... but he/she/it didn't

i was going to make a cake but i didnt do it.9 albo i didnt make it..

a cake but I didn't lub potocznie I was going to make a cake but I didn't

Nic w perfekcie. Pierwsza część może być: I was supposed to make a cake I was going to make a cake I was to make a cake i tak dalej Druga cześć chyba zawsze but I didn't
