Could you explain it to me?

Hi everybody, I'd like to know from any native English speaker or any teacher, if there are some differences of meaning in the sentences put in the inverted commas:

A: I think the guy's gone into the church.
B: I do not wanna enter there
A: "Me neither" / "Neither do I" (any differences of meaning? Or do I have to think that the first form is an informal English and the second one is a formal English)?

A: Which skirt do you like more? the blu one or the black one?
B: I prefer the black one.
C: "Me too" / "So do I" ( any differences of meaning?)

Uuhm..
yep. the latter choices are more formal than the first ones. "ME Too" and "me neither" are example of Informal English

Wanna is not a word in the English language. It is a phonetic representation of how many people pronounce "want to."

The rest is ordinary informal English.
