This isn't a TAAT, but I admit is inspired by it.
For those of you who are OLD, how many dates would you expect to go on before deciding to focus on someone alone? For me, date 3 has been the point... I knew enough by that stage to know if I wanted it continue into a budding relationship, and would generally make it clear on or after date 3 if that's how I felt. Luckily that's always been reciprocated for me... but I suppose if things aren't to progress, you generally know by dates 1 or 2.
Although i did string a couple of dates along when I much, much younger, I couldn't imagine still multi-dating at date 5 or 6!
