So, you spoke German at some point, but these days, you could not decipher a restaurant menu or ticket-vending machine? Not meant disparagingly, just truly curious...
I know someone who learned to understand German spoken on TV and would sometimes speak it themselves (on day trips across the border primarily I imagine), so they've got a good intuition for e.g. word gender (that their native language doesn't have) but they can write most words only phonetically and don't know the grammar. Thankfully German orthography is not like English', but it's also not a 1:1 map (cheese isn't kese; name arbitrarily has no h)
I can still understand sufficiently simple spoken German and decipher some written German. You could say I read it at the level of the two-year-old I was.
