How can you be humorous when others are late?

Does the subject want to ask "how do you reply humorously when others are late?"

1, you are a late major. Did you lose again this time?

I almost thought you were testing my patience and being late on purpose.

It seems that your concept of time needs to be updated. Otherwise, the next time we make an appointment, you can directly set the late alarm clock to synchronize with the current time.
