It’s too hot
Didn’t you know that Walmart’s “electronics” section is famous for attracting bare-chested women?
This woman is a perfect example of what has been put forward. There you go, this woman is asking about the best TV options, and she won’t let the heat distract her from her goal. This woman may be having hot flashes and has decided that neither her age nor her health could prevent her from doing her usual activities – like going shopping for example. It could also be that the heat was particularly unbearable that day and that she felt that no one could blame her if she went shopping topless. This woman is in any case very courageous.
