I think when the chips are down...or you are in a position of needing something that will really inconvenience them...like when my real friend picked me up at 3 a.m. at the bus station...when you take them into your house when it is too small but they have no job...when you help each other move, go through a divorce, a death, etc....of course you have to have some pleasant times too...hopefully fun and laughter...mg
