Window film isn’t so easy to install.

While my husband was away for business, my sister and I decided we were going to install Sun control window film in my living room. It really looked like it would be easy to install the sun control window film. We read all the instructions, had all the equipment we needed, and we thought we were prepared. We went to town and bought the sun control window film ‌I wanted and took it home. My sister was a handy person and did all of her own repairs in her home. She was more handy than her husband, and I was really sure that we could do this. She wasn’t so sure we could do this because she knew I couldn’t even paint a straight line without it looking ridiculous. Just undoing the window film and figuring out how to measure properly had me confused. She got this straight line tool that she brought with her, and a very sharp razor knife. She told me she would hold the tool while I cut along the edge. I looked at where her fingers were and where the razor edge was, and I told her I would prefer if I held the tool. She looked at me shaking and said no, and did it all. The more I tried to help, the worse the window film insulation was getting. After six hours of her laughing at me, getting mad at me, and then laughing a second time, we gave up. She said there was too much incompetence between the two of us to try installing window film. I threatened to kick her out when she said window film isn’t so easy to install when you’re trying to do with me. She laughed and I offered to take her for lunch.
