Just a second; loading will soon be complete. Almost there. Let’s wait a little longer. Something seems to be slow here. Is your WIFI OK? Just a little more patience. Or has it finished loading already? Shall we wait longer? Have your downloads ever been this slow? Dunno’ what to say. Are you downloading something? Well, if the the internet connection is otherwise OK, try reloading the page. Or wait a little longer. I’m out of ideas. I hope it’s going to finish loading soon. Something’s broken. Please try reloading the page.
