FIRST, SECOND, THIRD PERSON ORDER-

I and Tina will go to the market in the evening.❌

RULE  – Good manners require that ‘singular pronouns’ should be in second person, third person, first person (231) order. But in plural, ‘we’ is used before ‘you’, that is, 123 order. Same order (123) is followed while referring to unpleasant acts.

👉Example - 

you and I will be punished. ❌

I and you will be punished.✔️

⚫Note: Unpleasant act, so 123 order will be followed.

You, we and they should now get down to work. ❌

We, you and they should now get down to work. ✔️

⚫Note: (plural pronouns so order will be 123)
