I HAVE BEEN GOING OUT WITH HIM FOR ALMOST A YEAR AND FOR VAENTINES DAY I WANT TO GIVE HIM SOMETHING NIC E I DON'T KNOW WHAT TO BUY WITHOUT MY PARENTS NOTICING THAT I BOUGHT HIM SOMETHING. IF THEY DO FIND OUT I'LL BE IN HELLA TROUBLE. IWANT TO BUY HIM SOMETHING SMALL BECAUSE I DON'T WANT MY PARENTS TO KNOW BUT AT THE SAME TIME SIGNIFICANT FOR HIM. IF YOU GIVE ME SOME IDEAS I WOULD REALLY APPRECIATE IT . ~*~* THANK YOU ~*~*~* I AM NOTALLOWED TO HAVE A BOYFRIEND YET IM 17.
