Yes they can fall in love.
yes it is true to get a job!!!
no
Depends. How old are you? What type of "love" are you talking here?
Yes at 13 your body is going through changes and you may fall in love with a 57 year old.
act like you are 13 be yourself or just let him love you
Yes it is true as the 13 year must have started to have productive sperms and the 103 year old might still be active too.
The legal age to make love varies from state to state, but NO states allow it for 13 year old girls. So yes you can make love to a 13 year old but it will be considered statutory rape in the United States. In some countries of the world, it may be legal, however.
you love him ;)
A 13 year old boy can most definitely love a 12 year old girl. The age difference is not even that great that there should be any problem. I say for your age group, though, that you should hold off on dating until around the age of 15 or 16. You can 'date' when you're 13 or 12 but you shouldn't go out on dates until you're at least 15. It is totally fine for a 13 year old boy to love a 12 year old girl.
Doubtful if anyone age 13 knows that much about love yet. Only with maturity can one learn about true love, and sometimes that takes lots more time than 20 or 30 years or more. Most likely, the word 'love' can safely translate to 'like you a lot' ... certainly would not think, in this case, that this 13 year old boy was going to be your mate for life from now and into retirement.
Dating is OK; sex is not.
