Making someone's day.

2 things (among myriad of others) you can do to make someone's day (even a random person you passed when walking to school!): 

1. giving a smile

    - tapi kalau orang tu tak balas, jangan stress pula!

    - even better, give a nod with a greeting :D

2. contact those you're missing for
   - they could be missing you as well but ain't got time to give a whatsapp ;p
