confusions of a wandering mind - I

a social gathering.. 20 something and above aged homo sapiens of the feminine gender are seated on plush sofas..the waiter guy walks in and asks wat the ladies would like to wet their throats with.. some say nimbu paani.. some say cola.. some say fruit punch.. a select few go in for wine..all s well till here..the ordered drinks are catered for.. flutes and glasses are picked up and brought to the lips.. its here that the problem starts....
...brought to the lips.. a sip taken.. and the conversation stopped on account of the sip is resumed.. conv continues.. continues.. continues.... for god knows how long.. i keep this oh is that so look on..(courtesy my dog..) the whole while..(yeah i am there too.. with dire consequences threatened otherwise..) look down into my glass of nimbu paani after sometime .. and findin it devoid of the liquid decide to go in for a refill.. look around wanting to be of help to anyone who would like to join the bandwagon.. and find a couple of them goin in for a second sip..(yeah second sip..) and others jus cradlin their almost full glasses waitin for godknowswhom .. or was it for a straw...?At this point i am jus about on the verge of embarassment..
.. the wine drinkers at the gatherin are excused for the sipping syndrome..takin a sip.. letting the liquid leave the tingling sensation in teh mouth before creatin that warmth down the throat...mmm..that takes time.. either that .. or the wine' s vintage Chardonnay with the cost automatically leaving a lump down the throat of the person who dared to proclaim "the drinks are on the house everyone..!!" without first making sure there aren t any closet enemies round the place..relishing it becomes a necessity then..:)
its the lemon juice and the cola people whom I dont understand..the same set who empty a bottle of juice in five seconds flat take a hour to sip up half the quantity from a glass..why..?is it a demonstration of will power...an indication of throat cancer affliction durin parties alone...social etiquette..?..:-)..dont think the third one s an option even.. I have people to vouch for my public behaviour..(read parents..)..and wen I am at my normal best I keep my glass somewhat filled for around ten minutes..
so.. basically.....the only question haunting me when i see the sip..blah..blah..blah..blah......sip.. sequence is ..Why..??
