Is it bad of me that I don’t want to go to my family’s for the 4th. I mean I do want to see them but I don’t want to go sit out in the heat and all. We can’t sit inside their house cause it hot in there too and you can’t breathe from all the cigarette smoke. But on the other had my grandma is 83 and won’t be here forever.
