You wake up after a bad night, and look at the doormat, what do you see bills bills bills, OH what's that - a flyer for a pizza! Oh...another flyer for a pizza - this is getting old ;) So, you look again, and see your name written with an actual biro.
the smell of the ink, maybe a whiff of perfume.
the feeling inside, you know all the effort that's been put into it.
the thought that no other person has a letter identical to yours
Be grateful for them :) and if you don't receive any, send some and you'll be sure to get some back!
