Every occasion asks for a sweet and straightforward way of exchanging gifts. Gifts can be of any kind, starting from a small token of appreciation, including but not limited to accessories, cards, stationeries, etc., to a small amount of money as well.
You have to keep so much in your mind that you would instead let them buy a gift for themselves. So, why not do that instead? Get them gift cards from your favorite stores and let them buy themselves things that suit them the most!
