Please help me out, what extra words are needed to convey the incomplete nature of the actions?
A: What did you do yesterday?
B:
- I read books.
- I wrote my book.
- I built the wooden ship (which you had given me).
- I drew a picutre.
- I knitted a sweater.
- I climbed the mountain.
None of these actions were complete. B just did them for some time but not till their end. (Leonardo Da Vinci painted the Monalisa for 4 years. On one of the days in the middle he just painted it for a while and postponed continuation for another day)
