There is a habit of chewing something or the other; the one with Rahu in the 8th has a habit of smiling even in difficulties.
The 8th house is the house of sudden crises, death, and deep trauma. Rahu here brings intense, unexpected hardships.

They have a strange habit of smiling through the pain ("mushkilon mein bhi muskurane ki aadat"), hiding their deep trauma behind a calm face.
