<p>How about:</p>
<p>A) a family party with grandparents, aunts, uncles, cousins, etc.</p>
<p>B) a special event for your son and one or two good friends, like a play or concert, or overnight stay at hotel with waterpark? Depends on your son’s interests what kind of event he would enjoy. Prehaps something more active like bowling, golf or lasertag? </p>
<p>Main thing is ask your son what he thinks would make a special day, it may be much different than what you expect, and you should honor his wishes even if they seem odd to you.</p>
