2) This system doesn't work like Word/Excel! Why not? You've obviously set it up wrong.
3) I can't easily do Y. Make it do that. No, not that. Not that either. Now I've forgotten what Y was, but I've got this idea for Z, (unspoken: you can do that within the same quote, obviously. It's all computers.)
4) I can't remember how to do X or Y as I last did it 5 months ago and haven't touched it since. Show me again. I've lost the instructions you sent me.
5) I've failed to maintain Z so things are now broken. Fix it!
6) Can't YOU do it for me?
Repeat, and repeat, and repeat.
