Yesterday Josh and I went to his parents' house to pick up our gifts and keepsakes and a whole carload of stuff. He said "Hey, we need to stop and get something for my dad" and I said "Yeah, it's Father's Day! We need to get him something."
So, we stopped and got him a gift, pulled into the driveway and saw FIL mowing the grass. I was like "OMG! Is your dad mowing the grass?" and Josh said "Why the heck is he mowing grass on Father's Day?!"
We went in and told MIL we brought a father's day gift and she was like "What? It's not Father's Day! Is it?" and we all went to look at the calendar.
Josh and I are so crazy. I have no idea how we both individually thought yesterday was Father's Day. What a couple of dorks.
