difficult emails

What do you do dear readers when the tone of emails is hard to gauge? A couple of weeks ago a friend invited me down to see his new extension (fna fna). We rearranged the original dates to this weekend. I emailed earlier just to check whether this was still the go and got this in return:

Yeah I guess I could manage (sigh). Lets know your rough movements time (are you driving or bussing ?)

So what is this? Humour? I don't email MP that often so I don't know if this is his email humour style or am I feeling the fever and he actually doesn't really want me to stay. So what I do? Respond with some sarky sulkiness ... if you don't want me to come ... or just send him the ETA etc? The low level of enthusiasm is infectious.

Second email dilemma. Because I was expecting to be in Wellington next weekend and two of my dear friends who fled the grad earlier this year will be there for a summit meeting of sorts ... sounds quite exciting for historians doesn't it, I thought I would go down on Thursday and stay in a hotel and socialise with them mildly, as well as sort of try and arrange a *meeting* with my latest micro-crush. So I contact one of the friends who has given me the following options:

X and Y are keen for us to both go stay there on Thursday night - do you want to? It'd be real nice to all catch up together, but I am happy to go with whatever you're comfortable with. Otherwise, maybe we could have another pj party in NAME OF HOTEL Your call.

There seems to me to be a third option she's not giving me. I party with the Grad-uates and then escape back to the hotel alone. Well hopefully not alone.
So should I respond to this email with " Sorry XY AND Z I 'm planning to blow you off to get me some!
