Help to find one poem

Hello, my dear!

I ask to help me to find one poem.
About 20 years ago I heard this poem from lips of two different people, with each other unfamiliar. And both of these persons said that the author Yulia Drunina. I remembered only the last line "The main thing that there was no war" and that the poem small.

I devoted the whole 2019 to poetry. Began to notice at herself such phenomenon as "something with my memory became". Because of multitasking the brain began to glitch. Therefore for a training I decided to learn verses. Every week I learn one new poem. It is necessary to tell that I never understood poetry and did not love. Also perceived it only in the form of songs. But once in Denis Matsuyev's interview heard as he advised people who do not understand classical music (I too here belong), all the same to listen to it more often, and it will surely open. The virtuoso appeared the rights. The poetry by this principle to me opened and became much closer. Me it is direct here incurred. Both poets of a silver age, and children's, and Soviet authors. I select all verses by the principle: that it was pleasant to me. Anyway, each of the learned verses is connected with something. For example, "Oh, my timid hero" Bella Akhmadullina sounds in one of my favourite movies "Office romance".
But could not find that poem by Drunina.

Perhaps, I did not understand something or mixed? And at the poem other author?

One hope for you, young and inquisitive!
