I remember when me and my brother were walking from the primary school and back to our house when our neighbor's dog just freaking chased us.
The freak'n dog's snout touched the back of my knee whilst we were running.
Fortunately I was not bitten but me and my brother really got hibby-jeebez (whatever that meant). Oh my heart was like it had pumped 1 Liter per minute at that moment.
Then all is well again, it is just fun to run, but without some freaki'n dog chaisn' you.
