Nice. I don't know much Spanish beyond what you pick up just by speaking other Romance languages, but i did take a few years of French. I forgot a lot of it, but if someone speaks slowly i can understand enough to get by. Once in a while i will put on a movie in French (with French subtitles) just to not get completely rusty.
If you speak a Romance language natively it does make it fairly easy to learn others, though i have to say out of all of them Portuguese is the one i understand the least, especially when spoken. Like, i can half understand Italian even though i never learned it, and i can understand bits of Spanish, but Portuguese just really confuses my brain.
Compared to Spanish, it reminds me of how i feel when i hear Dutch while knowing German: I feel like it should be somewhat intelligible – and it is pretty intelligible when written, i can usually get a lot of it – but when it's spoken for some reason it stops making sense and i check out completely.
