writing is different - or at least the slant is different - which could be one hand vs. another ... isn’t HUSSEIN left handed?
H is left handed.
Writing slant can vary from day to day. It can also be affected by body position wrt paper. If you’re writing while sitting at a desk vs. writing on a notepad on your lap, etc.
To me, the handwriting matches, but perhaps I am biased and seeing what I want to see.
On the top “official” note 0b0la is writing “nicer”. If the bottom notes are his, and I think it possible, his writing is more sloppy. I can write “nice” and sloppy and they look quite different, but handwriting experts can tell. A handwriting expert needs to get on this.
