Should I be mad at my mom for knowing that I was bringing Hope over mind you it's 100 degrees outside and she told me she wasn't turning the air on well while we are their Hope begins crying uncontrollably so me and Ryan left because I believe she was getting over heated. What makes me mad rher most is i told her to turn it on and she just refused it just baffles me11
