I've tried and tried and tried and tried to sneak up to the house without the "trio" knowing I've come home - They know everytime!
I live in a condo and my car is a little distance from the unit. So I thought maybe they know the "chirp" when I set the alarm.... Nope! that's not it...
I've crawled under the window... tip toed as quietly as I can... They still know I'm home!
How do they do it?
Can you sneak up to your house undetected?
