But staying in the house for 3 weeks would DO IT!! That's what's so frustrating. If someone was overweight and they insist that they have NO IDEA of how to fix it and you tell them, start exercising daily and lower your caloric intake, but they INSIST, they still don't understand HOW to lose weight and continue to not exercise & all the while they shove cakes, pies, candy bars, and potato chips into his/her mouth, that would bother most people.
