WOW please don’t hurry to shed tears upon his imaginary tattoo: I understand you cry if he gets one, but so far, it’s just hot air. Is it legal in Israel to tattoo an underage without parental consent? A tattoo shop, which is how some people make a living, is hardly going to risk being fined because of his whims. Also, they avoid unreliable people like the plague, as they are harassed by customers who get something done and afterwards change their mind, want it removed (at the shop’s expense) and try to blame the parlor. I think a piercer or tattooer may figure out pretty quickly a thing or two.
I am curious about what will happen to that T-shirt after it gets dirty. Who will wash and press it?
Shabbat Shalom, don’t let him ruin your happiness, and in my humble opinion, trust your husband, your rabbi, your father and father in law – they are the people who can advice – they know you, they know the situation, they know the boy.
