same here! i was the youngest of my siblings (they were 8 and 9 years older than me) so i was favored and spoiled. i never took advantage of it. they didnt set curfew cause they trusted me (grandparents raised us) all my grandmaw ever said was "as long as you're home before your pawpaw leaves for work (5am)" i was usually home between 2 and 3. i went out, partied, drank, lost virginity at 16 almost 17, was open and honest with them....but rather the "dont ask, dont tell" as long as i was being careful and doing nothing stupid to get me in serious trouble.Not too much... I wasn't really one to rebel and shit.
the ONE thing that i did do that sent my grandmaw over the edge was get my tongue pierced. i was 17, mom signed consent form. mawmaw found out about it, screamed, threw luggage at me and told me to get out. i just rolled my eyes and ignored it cause i knew she didnt mean it. she got over it after a few months after realizing that i wasnt gonna take it out.
