I am annoyed when people say "I want to go to the loo". Come'on...do you really like to "go" to the loo? Do you enjoy that walk to the loo? So you want to go to the loo and come back. Come'on...say it. What do you want to do there? You just don't want to go there for the heck of it. be honest about why you want to go. Is keeping things simple that difficult?
