What would you do...?

Ok so today I was in our room watching a show I watch every Monday, well my SO knows what time it ends so he just kind of does his own thing for that hour. Anywhoooo I got up during a commercial break to see what he was doing cause he was super quiet. He wasn't inside and we have chairs on the front porch right in front of the dining room window. I look out of the window (he doesn't know I'm watching him) and he's going through his call log deleting numbers? I go outside and ask what he's doing to see what he would say, he said he was just on Facebook and watering the yard waiting for my show to be over? I asked him what numbers he was deleting off of his phone cause I saw what he was doing and his response was "I had like 15 calls today from different numbers that I didn't know I'm assuming they were telemarketers and I didn't need those numbers taking up space on my phone" I'm mad about this...am I wrong for feeling like I can't believe this?! Would u?!
