Yes, "call in" is kind of like "drop in" in this sense.

This usage in British English means "to visit a person or a place for a short time, usually while you are going somewhere else." 

For example: "I'll call in on my way home."

• 嗯，你們的英文感覺太好。這些小的動詞短語很有幫助，比如電話斷了，他們用cut off，不用disconnected -妖妖靈- ♀ (0 bytes) () 03/16/2022 postreply 09:21:07
