I'm having some trouble deciding whether or not to use "the" in the following sentences:
Jack washed (the) windows in his flat last week.
She's watering (the) plants in her friend's apartment.
My intuition tells me to opt for the article - the locations of both the plants and the windows were specified, which, as I understand it, would mean that "the" is necessary.
I guess my question should rather be: Is in his flat and in her friend's apartment enough to warrant a definite article?
