- Ваш характер я считаю совершенно сходным с моим, и очень рада; как две капли воды. (Ф. Достоевский, Идиот) — 'I consider that you have the same kind of nature as I have, and I'm glad of it - we are as like as two peas.'

Всё у них было одинаковым: волосы, глаза, носы, рты. Полная одинаковость - как две капли воды. (А. Рекемчук, Мальчики) — Everything about them was the same: hair, eyes, noses and mouths. They were like two peas in a pod.
