Crosstalk problem

I don't agree with either answer. I think so, too. First of all, do you remember that there is a story in front of this sentence you asked? It is said that Lao Guo received a text message, which is a bit like an affair. The last message said that he had just returned from abroad and had a watch for him, and then asked him to go to the overpass to get it. Later, the leader of their unit came that day, and Lao Guo was still thinking: "Should I receive the leader? Still coming to get the watch? " Finally decided to receive the leader, so I didn't go to the overpass. Besides, the last sentence is very clear. "There was an exam in our school. Everyone went to Tianqiao this afternoon except your father." In other words, the "gatekeeper" incident was set up by the school. This short message was not sent to Lao Guo alone, but to all the students' fathers, just to see what the students' fathers were like.

The burden is that Lao Guo didn't get on the overpass by accident, so his son feels that his father appeared for him, which reflects the psychology of ordinary citizens and is ironic.
