Your responsibility is currently to answer me and confirm the information in the registry. To meet that obligation, you have to take note of the people you have met with and the topics discussed.
In answer to one of my questions on this, if someone tells me they have no idea, do not remember that meeting and don't know who was there, I must rely on the word of the lobbyist who wrote down the actual information. Lobbyists do this within 15 days following the meeting scheduled for the month. They very often do so when they come out of a meeting.
If I ask you, you must confirm whether it is true or not. That is why my recommendation is to take good notes.
