Study Guide Nazir 21

Reish Lakish held that if one says "I will be a nazir" and another said "and me" and another said "and me", it is effective only if it was said immediately after (toch k'dei dibur). Support for this is brought from a braita. They also try to prove it from the fact that our Mishna listed only two people who responded "and me" and not more. But that answer is rejected as the tanna is not expected to count cases exactly as a peddlers count their wares. If so, why did the tanna not just list one person who said "and me"? Two questions are asked and sources, including our Mishna, are brought to try to answer the question. First question: when each person says "and me" are they connecting their statement to the first person who said they will be a nazir or to the person who said "and me" just before them? The second question is: when a husband nullifies the vows of his wife does it nullify them from the beginning, as if she never vowed, or is it cutting off the vow from right now? Most sources brought to answer the questions are rejected, but in the first question, they find the answer eventually in a braita.
