When I was chatting with one of my colleague, she sent me her old photograph. To that I replied-
nice pic, you are looking healthy.
To that she sent me-
thanks, but ironically I was thinner this time.
From my observation she was looking fat in pic and now she had lost some weight. but what she meant to say, I did not understand her reply? Was that sentence grammatically correct? I used the word 'healthy' instead of fat, so Was my selection of word correct this time?
