We always want to feel secured especially when we go travel. Peace of mind is what we need whenever we are away from home. I know it is normal to worry but, at least, we do not want to let it ruin our adventure.
If you you are frequent traveler or a person who loves to go on a long vacation, I bet everything in your house is well-kept. Unplugged unused electrical appliances except for the fridge, washer and dryer, and others. Let the ceiling fan run so air circulation in your home is balanced. Leave a light on so your house isn’t dark at night. Then ask someone you trust to check your house once in a while (if you have a garden, you can request him or her to water for you). But how about the mails? If you have a secure mailbox, that’s a good thing. Your mails are secured and you won’t worry about rainy weather to mess with your correspondences.
