Tip #4: Do NOT apologize for your gift while the recipient is opening it!
Yeah, yeah, I know how it goes. You couldn't find exactly the right thing. The store was out of what you had hoped to buy. You couldn't decide what size to choose. You didn't have enough time.
Whatever excuse explains your less-than-stellar gift, keep it to yourself!
A person opening a present should not feel compelled to console the giver before the wrapping even hits the floor. ("I understand. It's OK, really it is. Don't worry about it! I'm sure it'll be fine.")
Just hand over your gift, smile politely while it's being opened, and — when you inevitably hear "Thank you!" — muster your most sincere "You're welcome!"
(Oh, and don't forget to include a gift receipt.)
