Go over their house or
invite them over daily they might be worried
E-Mail them and talk to them online
Call them every week (at least twice a week)
Write letters to them telling them new news
Send pictures of the new news (if you got something) like the
sports section of the newspaper to hear how everything’s doing in sports
You should still respect them after they move example: call
them
You should still show your concerns example: you still listen
to them when they talk to you
