Why do people think....

...that if you're buying a pregnancy test you are hoping it's negative. 
We have been TTC for about a year and a half. I always buy all my ovulation tests and pregnancy tests at Walgreens bc of their reward system. It's the best. Today at Walgreens I was buying pregnancy tests (🤞🏼🤞🏼) and the cashier was surprised but how many points I had on my account to redeem ($20 off!!) I told her last time I was in here buying ovulation tests and had a coupon that multiplies your points by 10 and that's how I got so many. And her response was "oh..so you're like actually hoping you're pregnant?" Like shocked that some one buying a test actually wants a baby lol I was like uhhhh yeah I really hope I am. That's the look and comment I usually get but It's just funny to see some people reactions when buying fertility stuff. I get responses from people asking how I like this brand all the way too I hope you're not pregnant! Lol the last one may be bc I wasn't wear my wedding ring that day after I left the gym. Anyone else have funny experiences?
