Wow many things... about cities in Spain, as you have mentioned many are beautiful 😍 I think citizens don't know really how lucky they are living in this country that you know 😉
The dog story is touching, hope you can enjoy many nice walks but I understand the feelings about the little girl but she will understand (maybe) one day that you will take care well of the dog.
And about the market yes very modern but the "hole" is deep and a marble stairs not very easy for old people it should be long really... some elevators but also less aesthetic. Bit in general it's a pleasant place where to be.
And you are right about the color of the signature, we should also keep in kind the capital letters (for slaves since Roman times, "capitatis diminutio" or something like that).
We are humans with red heart ❤️ (although not easy to sign), not them, not the purple nor the black.
Be happy with the dog.
