To bi or not to bi

So you're tearing your hair a bit over whether to pick tha or is for a sentence, why everyone keeps giving you rules that don't quite work and why oh why in the first place should you have to pick?

First off, "why" is a legitimate question if you're curious as to the history. We'll set that aside for now. Why-oh-why does Gaelic need two of these on the other hand is less legit as a question. It's a bit like telling a date you *LOVE* them but they really need to do something about their nose... Their nose is part of what makes them them and if you can't live with the nose, then perhaps your dating for the wrong reasons... So this tha/is (it's technically bi vs is by the way) is just part of what makes Gaelic special. Not the same as French and Spanish. Part of its charm. So learn to live with it or even better, love it.
