<p>Are they really that important? Is someone at a major risk if he does not get approached by anyone the first contact night?</p>
<p>you might be…or you just haven’t been to a single house enough.</p>
<p>Assuming this is serious, yes you are at a major risk as a lot of houses give contacts to a large number of people for the first one. If you didn’t get any, I recommend going to new houses on the last day and hopefully making enough of an impression to get a contact on the second night.</p>
