Why did slave owners keep slaves birthdays secret

they kept it a secret so they wouldn't know how old they where or when was there birthday because  if they knew then they knew then maybe they would want a celebration or a day off work

what play?

explanation:

ok so like i went to wiki and looked up the (constitution x new "hammystan")and it showed me the picture it highlights new hampshire and says first and second session and than it says that they hit up the u.s and was like "ey dude that paper u sent us was adopted it bro thx" xd syays it all on wiki/the pic

i dont really like reading so i guess other people might not like reading either so   imma put the answer in bold italics
