"Mom, can we pleeeeeeease have a sleepover tonight?" Peter begged.
"No, honey, not tonight," was my tired reply.
"But Mooooooommmmmmm yesterday when I asked you, you said 'maybe tomorrow'. When a grown-up says 'maybe tomorrow' that always means yes!" he continued to beg.
I guess we have a communication problem because when I say 'maybe tomorrow' what I really mean is 'maybe you will have forgotten about it by tomorrow'.
