Why did my glass bounce when it hit a hard floor and then only on the second bounce did it break?!

I dropped a glass yesterday, from waist height on to a tiled floor. It bounced and then when it hit the floor again it smashed. Why didn’t it smash the first time it hit the floor?

I might be wrong so please correct me.

Glass actually bounces better than rubber assuming it doesn’t break. When glass hits the ground most of the energy of the impact returns to it so it bounces back up. The glass fell down and got a few cracks. When it came down again the few cracks made the glass fragile so it broke.
