Managing multiple plates: how do you manage small things like an incoming call from another plate when you are with one?

Managing multiple plates

Not here to say RP works as you already know it, but damn, it does!. I have multiple girls I'm going out with now, with one I´m having sex, with other starting to meet, with other relationship has come to an end. They message me, they call me as I do call them. The thing is how do you manage small things like an incoming call from another plate when you are with one plate?.
