On the task bar on your home screen there is a blue giftbox. When you click on it, you will have two screens available to you.
One screen is for you to send gifts to your friends & the other is a screen that lists the gifts your friends have sent you.
To send a gift, select it, then select the friend you want theo send it to. The gift you chose will show next to your friend's name.
After a gift is sent, it may not be available for several days or it may be available the next time your day changes.
Gifts are added or changed periodically, so you'll have to check each gift after the first time you send it to see when it will be available again.
