What’s the big problem which (our) German adjectives? Is it about the weak and strong declination and sometimes they are undecliend or what’s the point?

IMO german adjective are the hard part of the language . Der/den/dem/des Die/die/der/der das/das/dem/des fine I can leave with it.

But the way the adjective sometimes change with declination and sometimes doesn’ t always confuse me as hell Ich fahre das Blaue auto, Ich fahre ein blaues auto Ich habe im blauen Auto meine crush gekuesst Ich rüfe sie wegen des blauen autos an Also, unlike der/die/das I cannot just listen to the person I talk with and re-use the same gender
