An old friend comes calling

An old friend of mine wants to meet me. We were in the same school and were good friends. Later on he moved on and did well for himself. Unlike me he is a multifaceted person having various interests which were and are absolutely different from mine. Though he had never
misbehaved with me ever in school i feel as if he had just "endured" me. Though he never enjoyed chaating with me, I dont know why he persisited in doing so throughout the school days. Anyways he has moved on and is now enjoying his professional life. Now he has come back
to the city and wants to meet me. Should i meet him? People will generally think that this is a obnoxious question which shows my snobbish attitude.
However I have my own far different reasons. I would be very glad to meet him and discuss the good old school days. However i feel that once the nostalgic reminiscences of school days come to an end, we shall be left with no topic to talk about. Our interest are totally different and there is hardly any common interest. As a result he will get bored within an hour.........infact he will rue that he wasted his time talking to me.
He wants to enjoy his vacation as he has come back home after a long time. I feel that he shall enjoy more if he goes to a pub or a movie instead of meeting him. What do I do? Should i make up some lame excuse and avoid him? I am a straight forward person, so I cant discuss abt topics I am disinterested in. So no point in pretending like a person I am not. On the other hand whether he likes it or not I can meet him and talk about the past. What should I do?

Today one of my closest pals Manas left kgp for greener pastures. I bid him adieu with a heavy heart and wish him all the best.
