「私も同じく」をalsoとme too 以外でって英語でなんて言うの？

Likewise and ditto are both accurate ways to express you have the same thoughts or feelings regarding to what someone says.

Me too/ me also/ so am I/ I second that
these phrases express when something you say to mean that you are also in the same situation.

"I like listening to rock music."
"Me as well'/I second that/ Likewise/So am I/ me too/me also'

"I've finished work now, I am going home."
"Me as well/I second that/ Likewise/So am I/me too/me also"

I second that means that you agree with what the other person is saying.
I concur means to agree or have the same opinion with the other person..

Here are some imaginary scenarios:
A: Who's going to the cinema tonight? James - you're going; Henry, you're going; Arthur - you're going. What about you, Dave?"
B: "Yes, count me in too."
In another situation:
A: I'm taking names of people who want to go to the football game. How about you?"
B: "Yes, I'd like that."
And finally:
A: "We plan on taking the plane to Paris and then go by train to Antwerp. Do you all agree?
C; "Yes."
D: "I do."
B: "Yes, I'll go along with that

Instead of saying 'me too' or 'me also', there are other phrases that you can use which will convey the same message. Someone might say: I prefer coffee to tea and you might reply, 'likewise'. Someone might say: I am feeling so hot that I would welcome a very cold shower, and you might reply, "same here". This means that you would also do the same.

In a meeting you might have been attending, someone might have put forward a proposal to be discussed at the next meeting. Your immediate response would have been: "I second that". This means that you supported the proposal that he/she made.

A) Ditto
-the same thing again (used in lists and accounts and often indicated by a ditto mark under the word or figure to be repeated).

B) I second that
-The slang meaning is "I agree" or "I support that"

I hope this helps :-)

When we are in agreement we feel the same...we are in empathy;-D In conversation we can use lots of phrases like : "Same here" "like-minded" "I concur" or the very
succinct exclamation...Agreed... 100%

"Same here"
ex. "I turn 21 in march!, Same here!"
"Likewise!"
ex. "I'm so tired today!, Likewise"

"Same here" and "Likewise" are different ways of saying "me too" .
