Almost a year working at my company

I've been working in the company for almost a year now.

I've talked about it with my colleague and we both agreed it was time to ask for a raise :p

My colleague has been working there for a year and a half but she had an accident and had to stay home for a few months.

I think I'll see my boss just after my 1 year day and I'll ask for $5000, I think this is reasonable.

My boss is very kind but sometimes he makes me really nervous, so I dread that day a little bit. But on the other hand if I don't ask, I'm sure I'll have nothing. The worst thing that can happen is for him to say no.

I'm gonna start working on a good list of arguments :p
