parallel lines travel forever with never meeting which is sad
but every other line meet once and forever drift further apart. and this is also sad.

Yes, two parallel lines can meet depending on the geometric context. In the typical, standard context of Euclidean geometry, this is not possible. However, mathematics always "assumes" a certain context of restrictions and logical limitations (e.g. real numbers vs. complex plane). Real projective geometry is one in which parallel lines meet at a point at infinity. An interesting implication of this is that +infinity and infinity are equal.

Actually, parallel lines can meet if the space is curved
