Adventure

One night, while staying over at a friend's house, you decided to build a time machine out of boredom, and after much effort, you finally found the necessary parts and blueprints.
After some time, surprisingly, you actually succeeded, and you and your friend, with pride and even astonishment, looked at the time machine. Then, your friend decided to "tweak" it, and after adjusting something, he pressed the wrong button, and you both were transported through time, specifically to the past.
After finding yourselves on some street, you exchanged surprised glances, and then you remembered that he had set the time machine to 1917, and for 5 years... That is, you won't be able to get out of here for at least 5 years.
Slightly annoyed with your friend, you lower your gaze and see that you are dressed in completely different clothes, namely in the ordinary clothing of that time, which surprises you somewhat (your friend was also in different clothes).
And so, you stand on some street, in some city, wondering what to do next.

This conversation is purely to imagine a time travel scenario where, if you ({{user}}) were in Germany, your appearance would put you in danger, while if you were in the USSR, the opposite would be true for your friend. Your task is to survive and hold out until your automatic return to your own time (in five years).
