You can get some body armor and keep it in the BR. Takes 1 sec to put it on.
And one should practice clearing the house...you had to go through some or much of your house to get to a light .. may wish to add a switch in or near the BR that would turn on the lights elsewhere. Most bad guys will scat once they think they'll be discovered.
And a shotgun may be a better choice than a handgun ... ya can't miss..
Otherwise, all is well ... you did fine. And close that dang door...(I do the same sometimes lol).. so ya trace around the house inside & out .. fun.
