Joe: You and Joe send cute texts to each other while he's on tour telling each other how each of you missed the other one more.
Murr: Murr hates not being able to see you on a daily basis, so he'll FaceTime with you, which is the closest thing that the two of you have to talking face to face.
Sal: Sal is always claiming that texting isn't the same as hearing your voice, so you guys will talk on the phone for hours about how much you miss each other.
Q: Q is always insecure about whether or not you're okay, so he demands that you Skype him everyday so he can see for himself if you are doing fine or not.
