My pupils have a soft spot for my yoga sessions, any idea why?

Soft to the touch, hard to forget.

Soft to the touch, impossible to resist [BTBF]

Soft to the touch, impossible to forget

Soft to the touch, impossible to forget

Soft to the touch, impossible to forget

Soft to the touch, impossible to forget

Soft, heavy, and impossible to ignore

Heavy and soft, impossible to forget

Soft, round, and impossible to ignore

Too big to handle, too soft to forget

Heavy, soft, and impossible to ignore
