"very nice" - this is awful diction, objectively. Use less adverbs, stronger adjectives, etc..

But this particular phrase makes me think of serial killers every time I accidentally use it.

Fun fact: "I send you half the Kidne I took from one women prasarved it for you tother piece I fried and ate it was very nice" - Jack the Ripper

Furthermore every time I write something like "it was very nice" I am reminded of Clegg. The Collector contains some revoltingly bland writing. I don't know how he does it exactly, but it is brilliantly alienating.
