Gynybinė siena = Walls have fallen

Some walls are destructive, separating people,
Some walls are protective & necessary
Therefore

I am good at having no destructive walls
and caring for people
without selfish motives

But I am worse at building and
maintaining the necessary walls

My protective walls have fallen
The same as Vilniaus protective wall
Guarding the beautiful castle
Which is destroyed by never
ending wars

Vilnius protective wall, the capital city of Lithuania
A picture is made by me.
