It is around midnight but I am not sleepy yet because I took a nap.
I heard a sound "crack" from the living room right now. I went into the room and checked what's happened. I saw my husband sleeping on the sofa and glass broken into pieces beside the sofa on the floor. My husband seemed to have fallen asleep with a glass in his hand while watching TV. A splinter of glass had stuck in his hand but it didn't matter much. I picked up the fragments of the broken glass and vacuumed the room.
I'll make him use a tempered glass from now on instead of a crystal glass.
