My girlfriend is half Russian, half Armenian, from childhood speaks both languages freely, has a purely Slavic appearance (my mom’s genes won). She works in a coffee shop, has a pretty lush chest.

Two young Armenians come to us, approach the stand, order coffee. As I cook it, they begin to discuss my chest in Armenian. I, preparing the order, stretch their glasses and with a sweet smile in Armenian, say to them:
I know Armenian.
They had five copecks of eyes, stumbled, looked around. I am in Russian:
I am joking.
They breathed out, smiled and I again added in Armenian:
Per it is worth learning.
They left the coffee shop in a quick step, forgetting to give up.
