Fool around and be silly.
Go to shops and purchase things like sweets and ice lollies.
Healthy stuff so you can stay active enough for when your friends come round to fool about.
All the sweet and fatty things! (lazy or what??!)
Do fun and exciting things : joke around, play truth or dare and finish off with a horror movie!
All of the above, but after the scary film, have a HUGE midnight feast with sugary food!
Go up to her and tell a joke so she laughs until she has tears in her eyes (aw!)
Run to the nearest shop and buy sugary things like chocolate and bring it to her as a present so she is a bit more happier.
