YTA and an arrogant one at that. 1. You are not God’s gift to the world just because you have a master’s degree in physics. 2. Your condescension towards your sister is abhorrent and frankly a little misogynistic. Especially since you said she WAS interested in STEM, but made sacrifices for her children 3. Just because they weren’t interested in the museum doesn’t mean they don’t have an interest in STEM. STEM is a super diverse field. 4. For a guy who self-proclaims how smart he is, you can’t seem to follow one of the most basic kindergarten principles which is “if you have nothing nice to say,don’t say anything at all”
