The boys thought it was a regular fire drill but when they saw the actual firetruck outside their house they got very confused.

With the truck's siren blaring so loud outside their neighborhood, the boys got a little scared and confused over the noise.

Then one fireman came and entered their home to check their house. Even though the boys knew that firemen were the good guys because their dad is a firefighter in the United States Army, still their baffled look was evident on their face.

The older brother even refused and was hesitant when asked by his mom to help the fireman take off his suit when they were asked to go outside.

And when the fireman finally took off his suit, the boy's reactions were so adorable when they immediately noticed their dad and ran to hug him.

SSF. Brian Hessler, who has been away from home for 10 months, was finally home this time, in the arms of his boys.
