In some cases, it’s a good idea to give a friend a heads up even if there’s only a chance you’ll have to cancel. This will allow them to make a back-up plan if necessary.

When cancelling plans well in advance, emailing or texting can be appropriate, especially in more professional contexts. Try to put yourself in the other person’s shoes and use your best judgment when deciding how to contact them. Avoid texting simply because it’s easiest for you. [2] X Research source

If you think they may be very upset with you, make sure to acknowledge the impact of your actions and express remorse clearly. Apologizing repeatedly may sometimes be necessary, but the initial contact is often your best opportunity to apologize effectively. If you’re nervous, it can be helpful to plan an apology in advance. If it’s a less important activity, you should still apologize — but often something like a simple, “Sorry, can’t make it this time!” will suffice.

If you feel the need to lie, try to make it realistic. Avoid getting other people caught up in your lie. [5] X Research source

If you’re leaving your friend with extra tickets, you might offer to take on the burden of finding someone else to buy them.

Relationships become strained when one party starts cancelling with regularity. Cancelling is more likely to be met with forgiveness if it’s only on rare occasions.
