you will be ok if you waer a welding mask
I don't think it is OK to wear contact lenses if your eyes are not damaged because then you don't need them. All they will do is damage your eyes and when you are wearing them you wont be able to see because you need a prescription/its not the right prescription!
While it is not illegal, it is not okay! Five years old is too young to understand such relationships. And any sexual contact would be very illegal.
Sure, why not? That's what MySpace is for, "a place to meet friends", so why not use it do reconnect with old ones?
yes it is okay to have it once in a while
No, it is not okay. It is going to be illegal to have sexual contact with anyone under the age of 12.
no, the integrity of the lens has been jeopardized due to the crack, replace it immediately
So long as you don't wipe it with anything that will scratch it up you should not worry.
yes it is okay to have your hair tied up while having nits
Not while your seeing him/her!!!
Sure.
Speak to your dermatologist
I would say that it would not be okay. While the 16 year old has probably reached the age of consent, the 13 year old may not have even started puberty. Any hint of sexual contact could result in criminal investigation.
