Hello,
Today I read your post very carefully, you showed amazing pictures of your former university and refreshed old memories, got food packed, made beef patties, but even after reading it very carefully and eagerly, I could not find out which country your passport was stamped for. Yes, you had also written in the beginning that you will share it with us later.
And let me tell you a very secret thing, in your first paragraph you have written vaccination instead of vacation, but I thought that maybe you are going to a country where vaccination is necessary before going.
Inshallah, enjoy your trip,
