Xiao Zhang asked Xiao Li to go to the shopping mall the next day. Xiao Li said, If it doesn't rain tomorrow, I will go climbing. The next day, it started to drizzle. Xiao Zhang thought Xiao Li would not go climbing anymore, so he went to Xiao Li's dormitory for him, but he knew that Xiao Li was still going to climb the mountain. When the two met again, Xiao Zhang blamed Xiao Li for breaking his promise, since it was raining, why did you still go climbing? Xiao Li said that he did not break his promise, and Xiao Zhang's assertion is illogical.
The statement 'This argument between Xiao Zhang and Xiao Li is meaningless' is appropriate regarding the argument between the two.
