I was spanked quite a lot actually, sometimes even by my older brother when he was visiting us (he used to get angry at me every single time at least once). Once my mom hit me so that I even got nosebleed. I remember hitting back every time I got spanked so maybe they gave up spanking when I grew up too strong..
I think I could hit my child if I ever got one but not without a very good reason (he or she doing something really bad like torturing animals, stealing etc.).
