I loved this prompt. Regenschirm means umbrella, in case you're wondering, and Teller is plate.
das Wort (word)
Erik speaks five languages fluently, but that doesn't preclude him from making mistakes. Sometimes he forgets the words for things – silly, domestic things like Regenschirm and Teller – and then Charles smiles as he struggles to remember.
Sometimes, he speaks German, because Charles likes hearing it. But here, too, there are problems, words he can't say because of what they now mean. Camp. Train.
Erik may be good with words, but he understands that, sometimes, they're not necessary. Charles doesn't, so he's currently struggling to form a sentence, probably about not being drunk enough for plausible deniability.
Erik just kisses him.
