Ai or Ishou ni ?

こんにちわ、みなさん。 I have a question here. 教えてください。 In Rocket Japanese Lesson 2.4 Catching a Ride: あっ、　タクシー　が　き　ました。　*あい　のり*　します　か？ Ai nori (あい　のり) means to ride (the taxi) together. So what if I say "Ishou ni nori" (いしょう　に　のり）？ As far as I know, ishou also means together. Can "ishou" can be used as a substitute? ありがとうございます（in advance）　:D

Konnichiwa Wong-san! You are correct. You could substitute the questions: あい　のり　します　か？(Ai nori shimasu ka?) With another question like: Issho ni norimasen ka? This translates as "Shall we ride together?" However, just note that the word あい　のり (ai nori) is specific to a "car/taxi ride" - and you can probably think of it as equivalent to "carpool" - where as "Issho ni norimasen ka?" can be a question refering to any kind of vehicle or thing that you ride on. You could be referring to a plane ride. Hope that helps! -Sayaka :P
