Błędnie: It was a really feral day for us- the car crash, the delay and the whole row have driven me mad. Poprawnie: It was a really unlucky day for us- the car crash, the delay and the whole row have driven me mad.
Przymiotnik "feral" oznacza 'dziki', 'powtórnie zdziczały'. 'Feralny, pechowy' to "unlucky".
