How do you react to calls from LBs...

[guydesavoy]

If and when I do call them back, it's not just for a chat

They can be strung along or avoided for as long as you want, until you're ready. If not, then they shouldn't get your number in the first place

I have never received a call

So many good answers but it really depends on the person that owns the phone and what they are doing at the time, what day of the week it is, which activity are you involved with, who is calling and at what hour. Also, you current state of mind and energy level. Perhaps another factor would be, is if you have your phone handy and aren't in the shitter or shower
