Does my saying "no" to someone who asks "Are you drinking?" while I am drinking count as a lie, knowing that the questioner is joking?

Lying is informing about something contrary to its reality, and truthfulness is the conformity of speech to reality. This definition applies to both jest and seriousness alike. Therefore, one must refrain from lying even when joking, based on the saying of the Prophet, peace and blessings be upon him: "I guarantee a house in the middle of Paradise for one who abandons lying, even if he is joking."
