Walmart noseyness!!!!

So I went to Walmart bought some cheapies and a few frer. Went through self checkout to avoid the awkward questions that I have faced in the past. Low and BEHOLD the lady watching the self check out. Comes up to me and says " Good Lord, how many test do you need? You know it only takes one right?" I smh and said well some of us get overly excited at 32 years old to see a bfp when we have never seen one. I'm praying that I get a chance to see that and I'm excited for a change. Why must I always go through this.
