Show them that you really love each other
Honestly, you can't convince them. Either they will let you or they won't.
if your parents wont let you get sponsored, well, id yell at em.
you say parents are going with
say please
I have the same question!
you ask them
make a deal with them and stick to it :)
tell them you want rats
be a good kid
come out of the closet
You don't convince them of a "play date" that stops around are 3-4...and the point of play dates is for parents to put kids together to play. You are up front with them and tell what you want to do with the other person, as well as when/why.
Be practically perfect for the whole day, then at like 7:00, ask if you can stay up 1 hour later than usual in the politest way possible. Continue until satisfied. (Hint: decrease the amount of time you ask for each time you ask. :)
