I would not worry too much about it if it looks reasonably straight. It is just a nose. Mine has been modified too and it adds character.
You aren't going to cover this one up at work. Just face the music. If anyone asks (everyone will!), tell them your wife hit you and keep repeating and tell them "don't ask" until they aren't sure if you are serious or not.
I went hunting one night many years ago, mid-week, leaving work early with an excuse. Exciting wild boar hunt, taking running shots with a high powered rifle, got some scope burn in the process. Next day everyone at work kept asking what happened ... the wife story diffused things nicely.
