Learn English – Difference in meaning between ‘in view of’ and ‘in the view of’

Sorry expresses more regret than excuse me does.

If I'm trying to leave the room and you're in my way, I'll say "Excuse me." I recognize that I'm inconveniencing you by asking you to move, but the inconvenience is very small, and I don't expect you to be offended by the request. People often say "excuse me" when they commit small violations of etiquette, such as sneezing loudly.

If I accidentally step on your toe while I'm trying to get to the door, I'll say "I'm sorry!" I didn't mean to step on your toe, and I regret injuring you.

It's generally regarded that the two are grammatically acceptable pronouns in American English. However, "one" is also considered to be more formal than you and excessive use of the word can lead one to appear as overly haughty or pretentious. One can use the pronoun "one" as an impersonal pronoun that's representative of the average person - this generalization can lead to a sense of social superiority.

One of them isn't really more correct than the other - however, "one" can sound rather pedantic when used in relaxed or informal settings. This is realized in the object case when "one" sounds quite odd - "When lemons are handed to one, one should make lemonade."
