I asked my dad what his all-time favorite Father's Day gift was.

He didn't even hesitate. He pointed to the lopsided, hand-painted mug I made him in kindergarten and said, 'This one. It reminded me that the best things in life don't cost a thing... and also that you're worth every penny.'

For Father's Day, I got my dad a brand new smart thermostat.

He thanked me, then spent the rest of the day setting it to the exact same temperature it was before, just with more authority.

I asked my dad what he wanted for Father's Day, and he said something to warm my heart

So I turned up the thermostat, now he's ecstatic and our energy bill is through the roof

I tried to bake my dad a cake for Father's Day, but I accidentally used salt instead of sugar.

He took one bite, made a face like he'd swallowed a lemon, but then just smiled and said, 'You know, this is exactly what I wanted. A reminder of how much effort you put in.' And I realized he's been appreciating my 'best efforts' his whole life.
