Let's say I have a to-do list: Email Sharon, Peter and Mike. Yet as soon as email them, it generates three more items on my to-do list for a few days later: Chase up replies from Sharon, Peter and Mike. Because invariably they will not reply.
Even worse is when Sharon says she will get back to me by 10am Friday. It's now 4.30 and I haven't heard anything. Yet other things are in place now that were dependent on her reply this morning.
I've really had enough with it all today.
