Testing From All Angles (6)

Mr. Gu is acting strangely these days. He used to fill his time in the evening with social engagements as much as possible, but now, he tries to refuse all social engagements in the evening. 

He asks me to drive him to the shopping mall everyday before six o'clock. Then each time, he brings home a luxury good from a different brand.

These days, Mr. Gu seems like a family-oriented man.

However, except for him, no one knew that before Mr. Gu left home in the morning, he had a smile on his face. However, the moment he got into the car, he immediately switched to a cold face and kept it the whole day. When he went home in the evening with a gift in his hand, he converted back to his look from the morning, gentle and cultivated.
