1. Snape hated Teddy weekends and tended to make himself scarce whenever he could. Once every month, Andromeda would drop the noisy brat off Saturday around noon and pick him up Sunday evening, plunging Potter into tedious domesticity. From the way the obnoxious six year old hid between Potter's legs every time he came out of his lab, he'd always assumed the feeling was mutual.
2. For all that people seemed entranced by the composure of their interactions whenever they were thrown together by these events, Snape always held that an older Potter was not necessarily a better Potter. Certainly not any easier to bear.
3. Harry couldn't help but feel a little bit gleeful at the prospect of being Snape's boss.
