Apology Letter for Letting Down a Friend

Dear [Name],

I want to start off by expressing my sincerest apologies for my absence. I understand that my absence has caused a disruption in the team and I take full responsibility for my actions.

I know that I should have informed you of my absence ahead of time, but I was unable to do so due to [reason]. I understand that this was not an acceptable excuse and I am deeply sorry for the inconvenience caused.

I am aware that my absence has caused a lot of disruption in the team and I understand that this is not acceptable. I am willing to do whatever it takes to make up for the time that I have missed and I am committed to making sure that this does not happen again.

I am also willing to take on extra tasks and responsibilities in order to make up for the time that I have missed. I understand that this may be an inconvenience for the team, but I am willing to do whatever it takes to make up for my absence.

Once again, I apologize for my absence and I am committed to making sure that this does not happen again. I understand that my absence has caused a disruption in the team and I am willing to do whatever it takes to make up for it.

Sincerely,
[Your Name]

Dear {Recipient},

I'm very sorry for hurting your feelings while we were at {event/location} on {date}. I didn't mean to {make you cry/upset you/make you angry/etc.}, and I hope you know that I would never intentionally do something like that. I've felt bad since that day, knowing that I've caused you so much pain.

I hope you can find it in your heart to forgive me. I value you tremendously as a {friend/colleague/sibling/etc.} and I want nothing more than to get our relationship back on track. Please let me know what I can do to make it up to you.

Sincerely,

Dear {Recipient},

Please accept my apologies for not attending your party {last night/yesterday/etc.}. I wanted nothing more than to celebrate {occasion} with you; sadly, {reason} hence I couldn't make it.

I would have {called/texted}, but I knew you were busy with {host/hostess} duties and I didn't want to bother you. I'm sure all your guests had a wonderful time. I'm a little jealous, actually.

Anyway, {I wish you a happy birthday/congratulations on your well-deserved success/etc.}! Let's meet up soon, shall we?

Warmly,
{Your Name}

I'm sorry for not texting back right away {last night/yesterday/etc.}. Please know that I would never ignore you on purpose. I had simply {forgotten to check my phone/fallen asleep/etc.} and read your message just now.

Best,
{Your Name}
