Apology Letter For Ignoring A Person

Dear {Recipient},

I'm so sorry I ignored you at {event/location} the other day. There were several {matters/people} that needed my attention at the time, so I apologize if I came across as rude. Please know that it was never my intention to ignore you. I had actually planned to go up to you, but unfortunately, circumstances prevented me from doing so.

If you're free this week, I would love to sit down and chat with you one-on-one. How does {coffee/lunch} at {name of cafe/restaurant} sound? Please let me know your availability.

Sincerely yours,

{Your Name}
