The thing that bothers me pretty much right now.
I know that I should use I thought they were ... in most cases.
The thing is, let me put it the straightest way I can.
The other day I saw an offer of the shoes and in the description was mentioned only 9. I took for granted that it was 9 in US sizing, but it turned out that it was uk. Now the question, because the shoes are still for sale and they still exist - in that case, should I say "I thought they are 9us", or no matter what should I go with "I thought they were 9us".
