Bingley,

Moitié moitié (half & half)

The first <to> is used for expressing an aim/intention to “welcome”. My aim is to welcome daurelie so I am using it as preposition.

Well caught on the second, it is a preposition. That’ll teach me to be talking grammar at 10:42 p.m. (our time) when I got up at 5:00 in the a.m.
