Happy Birthday! Glad I no longer have a teenage sister. I hope this means that you will grow up and be more mature, not so childish all the time :o) He he he!
Hope all is well in England! I bought a stamp to mail off a "present" from the kids, but need to actually put it in the mail, so you can celebrate your bday again in a week or so when I remember to mail it off.
Behave. Don't have too much fun :o)
