My parents used to ring a bell whenever it was time to eat. Omg that bell was so annoying--especially in the morning.
DH needed a bell for work so we ordered 2. One for him and one for home. HAHA. It'll be a nice way for us to get the kids downstairs or to the kitchen without having to yell or text.
Did your parents use bells or etc. at home when you were younger? Will you?
