It's not every day that people all around the world get to celebrate Mother's Day. Mother's day is an annual celebration that only happens every May 11. The event turns social medias such as Facebook and Twitter, into a traffic of all kinds of Mother's Day greetings, from solo pictures of mothers, or mothers with their family, to a simple message to show appreciation and love.

How you say "I Love You" or tell a mother you appreciate her is a personal choice. While older men and women are more conscious to what they say, kids on the other hand, is a different matter. They can be brutally honest when they want to be. Below, Buzzfeed and Viral Nova tell us how kids show their mom their love, and what they write on their greeting cards for their mothers. Young children are cute, to the point that they make you laugh. But sometimes too, they can be tactless and the truth hurts, as the saying goes.
