30 degree heat wave!

I just had a little bit of a funny interaction with my cousin who lives 1700 miles away from me. I live in NJ she is in Texas. She posted something saying that they were having a heat wave and it was only 30 degrees out. I told her it is the same here and i have my windows open! This is true it is 30 degrees out and I do have my windows open. Is it warm enough for this not really but I am tired of being sick. Germs and all the little crawly things we can not see love the heat and them love to get inside us and make us sick. So I try to open my windows and air it out as much as I can tolerate it. I try to wear more layers and keep my house a little cooler to try to not breed those little creepy crawlers. Now that I am sick I am even worse about opening my windows every day and trying to stay warm with out making everyone else feel like they are in a sweat box! I just want to know where my global warming is!
