You gave her noogies, scrubbed the bathroom floor with her toothbrush, and kicked over all her Lego houses. 

You guys were more like gladiators than siblings.

For a lesson in sisterly harmony, look to Susan and Julia Chu, owners of the just-opened Tbar. They’ll teach you about various types of teas while you enjoy a blended, iced, hot, or fizzy concoction in their relaxing corner space.

They offer Steep, loose leaves with flavors like Safari (a fragrant blend of green rooibos from the African bush); Shake (different tea-based lattes or bubble drinks); and the delicious Green Tang (green tea, lemongrass, and ginger).

Fizz, a refreshing concoction of herb and fruit tonics over Perrier and ice, will teach you about getting harmonious results from incompatible elements.

That should get the family dynamics brewing.
