  We show that square(theta) implies that there is a first countable
<theta-collectionwise Hausdorff space that is not weakly theta-collectionwise
Hausdorff. We also show that in the model obtained by Levy collapsing a weakly
compact (supercompact) cardinal to omega_2, first countable
aleph_1-collectionwise Hausdorff spaces are weakly aleph_2-collectionwise
Hausdorff (weakly collectionwise Hausdorff). In the last section we show that
assuming E^omega_theta, a certain theta-family of integer valued functions
exists and that in the model obtained by Levy collapsing a supercompact
cardinal to omega_2, these families do not exist.
