Human: My windows in my house are drafty. How do I fix this? Assistant: 
One way you could fix this is to replace the windows with new energy-efficient windows, which will help keep the cold air out and prevent drafts. Another option is to use weatherstripping, caulk, and insulation around the window frames to create a better seal. You could also install clear plastic film over the windows to help reduce drafts, as well as using heavy curtains or blinds over the windows.
