It's about time!

Believe me!

First of all I have to say, that I have not much FREE time in the afternoons and evenings so I'm writing now... by the way what time is it ? 0: 52 a.m. is that evening /night for the Spaniards or morning for the British, whatever... I'm looking after my nieces in the afternoon-evening-nights and I brought them/myself today to the Acuarium in BCN, I'm exausted! not complains though...

Well my idiomatic expression is... YOU ARE BARKING UP THE WRONG TREE, It means that you are wrong, your are not understanding the matter, it's not true, ect. I don't know where it comes from so maybe you can help me to find it out... Thanks

See you tomorrow, sorry today
