If I happen to be caught in the sticky situation where I don't have a gift for my friend's party, I wouldn't panic! I would first think of something that would be more important to her/him, possibly a card or maybe even our friendship. And if I couldn't resort to that, I would text/call them before their party and politely and apologetically say, "Hey, I totally forgot about a gift for your party, and don't have enough time to run out to get one. Is it cool if I get a gift for you next week?" Or, if you really don't want to get a gift for this person, just say, "Is it okay if you don't receive a gift from me this year? You still mean so much to me!" And hopefully, your friend will understand!
Skunks stink mainly because of the "...oily chemicals called thiols. These are sulfur compounds..." in their tail spray. These chemicals, containing sulfur, a very bad-smelling compound, are what make skunks stink the way they do.
