I'm old enough to have mainly used cursive in school and I definitely had the thought that it seemed like a vaguely arabic-inspired cursive when I saw it the flourishes on the D.
But from looking at examples of cursive on google images, it seems like that form is no longer as prominent.
We've now established that you went to school in Arab, and this is why you wrote D in Arabic, for at no point did you counter this logic.
