Common App...Please Help

On the common app, when they ask for your parents’ occupations and employers, is this information really that important or rlevant. I really have no idea what my dad’s job title would be considered. We’re not that close, I usually see him once a week but I’m working so I haven’t seen him in a while. Should I leave this blank or write Unknown. What would colleges think of this? Would it be a problem?

<p>It isn't really crucial to get any official wording, just describe what he's doing.</p>

<p>what would you say for working at walmart? lol...I think that's what he's still doing, we're abviously not that close.</p>

<p>retail? (+chars)</p>

<p>thanks! that'll work</p>
