I just did something yesterday about the same way... Filled up my lawn mower and hit the yard and finally came back in under the trees to sit a while and cool down...
Looked down at the mower and its missing the fuel cap - yup I guess I didn't put it back on. So I went and walked the yard a bit knowing no way would I find the cap. Nothing showing up and on the way back to the tree I kicked it up out of the grass not even looking for it haha...
There was two butterflys close by too... I was kinda of following them back as they were staying with me and they made a jog in their route which I did the same... Probably my dad telling me I need to more observant... I tipped my hat to the butterflys and headed back to the shade under the trees...
Fun when you get in the mid 70s I guess...
