to minimize the stuff in your yard getting robbed, if possible, don't leave things/valuables outdoors overnight or when no one is at home. grabe, kami nga, pati yung batya na may yupi na, iniwan lang namin overnight, kinabukasan, wala na
getting robbed by someone who is already inside your house is even more irritating. lets just be careful how we screen our helpers and the amount of trust we give to them.
me, i screen my househelpers thoroughly since i entrust my children to them when my wife and i are at work. i also teach my kids to report any "suspicious" behavior to us, and that they (the kids) should never be afraid of the yaya.
