not paying attention; lost in thought
心不在焉；陷入沉思 (xin bu zai yan xian ru chen si)
"He looked completely spaced out during the meeting."
"他在会议上看起来完全心不在焉。" (ta zai hui yi shang kan qi lai wan quan xin bu zai yan)
to help someone out of kindness
the point where progress stops; the end of something
to make sure the team remains focused and organized
to set a limit on what is acceptable
to fall deeply in love
to be lost in thought or imagination
