I miss not having a sister, maybe I would have been too protective of her, who knows. But I would Ave given her this advice for valentine's day:

It is only 24hrs don't allow him make you spend the next 24 years regretting what you did on that day.

We guys have one thing in mind on that day, if you are a girl below 18 take note, be wise.

Least yhu can do is advise em....I got a 16 year old sis....Pretty matured for her age am five years older but we get along fine...one thing ave learnt is yhu can't hide em forever....Always tell them to be prepared to take the heat for all their actions.........Try not to be too judgmental....#foodforthought
