How do you know if someone add you as friend?

On funadvice, how do you know if someone add you as friend?

You get notifications sent to your email if you have the option enabled.

Because you're only 13, you should receive notifications by default so you have to actually accept a friend invitation - unless you turned that off.

Okay, thanks

You usually receive an email saying so.

If you look in the Friends Activities you see it will say what your friends are doing,like if someone commented a friend of yours,it shows up in that area same with answering someone els's question or if a friend asked a question. When someone adds YOU it will say funadvice added thedude as a friend. That's how you'll know.

u get an email that tells you and they will show up in your friends

I memorised my list and its quite easy ... only added two people Yummeh and Colourofme.

when people add me I can see the number next to my friend list so when the number increases, I sent a comment to say thanks to the person who added me

Thanks for the answers evryone. My email wasnt really working so I didnt really find out until you said it
