first holiday they may stay in the boarding house. but after that, other maid in your building or in your garden will tell her where to go or date her next holiday....they will exchange info, phone no, will go to same church, or same place to stay, even will sms to exchange info and chat. don't worry!
I have bad experinces with my few prevoius indo maids, they will bring my son to play in the clubhouse but they involved lot of gossips, borrow $...etc..give me lot of troubles...so that i hire philipino maid this time (as i know majority of indo maids in my buidling)..I have told her not to talk and make any friends in this building as they like to approach you and make friends w/ u but the purpose is just borrow $....and so far as i can see my maid is pretty simple, not try to make friends with others....i don't know where she can go during her rest day?
