We don't have household mail delivery where I am... so it is a trip to the PO Box. I do a silent 'WooHoo!' when I see a letter(s) in the box. I try to read them in the car, but if I have the kids with me, or I walked to the post office, I hold off until we are home (and the kids are busy playing) before I open them. I read it through and then put it aside until I can sit down and reply, when I will re-read them as I am typing/writing back to them.
