context: When I was at camp last summer, I wasn't allowed to use email, so I had to write a letter to my parents to tell them that I wanted to come home. I sat on my bunk with my notebook propped against my knees and thought about what I wanted to say. After a few minutes, I decided I knew what I wanted to say, so I picked up my pen and started moving it across the paper. First I put the date in the upper right hand corner. Then I wrote "Dear Mom and Dad" on the first line. I kept writing all the words I needed to use in order to convince my parents to let me come home. Then I signed the letter with my name. I folded the letter in half and then folded it in half again so that it would fit in an envelope. Then I put the letter in an envelope. I taped the envelope shut. Then I stuck a stamp on the upper right corner of the envelope. I wrote my parent's address on the middle of the envelope and then I walked to the camp office and gave my letter to the secretary so she could mail it for me.
question: Were they sitting while they wrote the letter?
