My 4yo told me I'm the best dad ever and it absolutely destroyed me

We were just playing in the backyard, nothing special, throwing a ball around. He looked at me and said 'Dad you're the best dad ever in the whole world.' Now I'm sitting at my desk at work trying not to cry. Having kids hits different man. I wish I could bottle this moment up. Anyone else get absolutely wrecked by stuff like this? Makes all the hard days worth it.
