Thanks Serge_spb!
I'm from England. There are way more mistakes in there than I thought, mostly simple ones.
Кажется, при попытке найти свои очки под прилавком
My original should have been :
Кажется, при попытке найти её очки под прилавком
So it is permissible to use 'свои' here rather than 'её', even though the girl was only once mentioned in the previous paragraph? That's interesting, I thought that you could only use свой etc when the person has been mentioned in a previous clause. It makes sense though, as its obvious that this is the person being referred to.
шумные птицы not птиц? I thought because they are animate.
молчанне (?) и млекопитающих was supposed to read 'silence, and mammals' I was trying to be clever I suppose...
вверх ногами кот (?) upside down. My cat sleeps like like that.
Thanks for reading that, I'm glad that most of it seems to make sense.
