My first little came to the house, and was very quiet, but I knew there was something about her that I just loved, her honesty I suppose. She came to the house one night while she was new membering and we hadn't chosen bigs/littles yet and we sat out in front of the house and talked for like 3 hours about absolutely everything, and we clicked for that and she was going through some stuff that I had been through. In that way, I became more of a mentor to her. It was pretty much decided that I would be her big straight off the bat. and like Violetpretty said, I pretty much chose our family. I like to groom them for Eboard positions and to be more involved than other family lines.
My second little I contacted through an email our rush chair got from her when she saw a poster for COB. Our rush chair was away that weekend, and I was bored so I im'd her and we talked online for hours, and we hadn't even met! she came through COB and I just loved her.
I was also very close to my 1st little's little (my grandlittle) and my second little's little as well. I'm also close to my great grandlittles even though I graduated, I make a big effort to talk to them, facebook them, and visit at least once a semester. I try to be there for when they get in too.
My first little was President after I was, my second little is currently President, one of my grandlittle's was house president, another is now Social chair, and I'm getting my great grandlittle's ready for eboard too
