Be careful when you invite people for your birthday party. A 16 year old girl Thessa from Hamburg, Germany posted an open invitation for her birthday party on Fecebook. It was supposed to be private, but the teenager forgot to change the settings.
When as many as 15 thousand Facebook users answered to this invitation, Thessa tried to cancel the party, but unfortunately in vain. Crowds gathered in front of her house in the day of expected birthday party. According to Hamburg police records approximately 1.600 guests arrived. Most of them were even wearing shirts with Thessa’s photos. Fortunately, policemen were able to manage the situation. A few people were arrested and one policeman got hurt.
Really, after so many such incidents Facebook should ban posting open birthday invitations.
