I saw my sister's profile on one of those matchmaking sites

Unless your sister is 12 and trying to pass herself off as a woman seeking men, stay out of it.

Her life is private. And just because you feel men have privileges that women can’t also have, that’s no reason to get into her life.

Say nothing.

I agree. If your sister is over 15, it is definitely none of your business.

How did you wind up on a matchmaking site while working on your science homework? I'm guessing your sister is older than you because if she was younger you would have talked talked to her yourself. If my younger brother was skirting dangerous site, I would have talked to him....I was alway protective of him. Calling a site a matchmaking site is nebulous.....I'm not accusing you of viewing verboten sites, but you mentioned you found a profile that was very familiar to yours. Depending on your ages...maybe your parents should know that both of their kids are online trying to meet folks. I don't know, but you should at least consider my questions. Here's a hint, I'm a mother whose children are adults, if one of my boys came to me to tattle on another.....I would really want to know how they came across the information, I certainly would want my children to be safe....but it might make me curious if one told me that they found the other involved in a 'risky' site..I know it' s hard to believe, but your parents remember what 14 or 15 feels like, you just don't know what its like to be 40.
