Because

I'm only up at this time of day because I have to go to work.

I'll buy that on the credit card because we're struggling for money.

I buy the cheapest tobacco because I really can't afford to smoke.

I buy a Sunday newspaper every week because I'm retired and can afford the time and money to do so.

I wear my hair in a 'man-bun' because I think I look cool.

I wear shorts in the winter because I don't feel the cold - much.

I'm this shape because I don't look after myself.

I'm buying alcohol because it's Friday.

I'm buying alcohol because I'm going to watch the footy.

I'm buying alcohol because I have a drink problem.

I wear this England football shirt because it makes me feel like I belong.

I buy 'energy drinks' because I really believe they give me energy.

I'll have this bar of chocolate for my breakfast because I'm not organised enough to arrange a proper breakfast.

I smile all the time because I'm a happy soul.

I'm excited when it begins to snow because I can remember what it felt like when it snowed when I was a child.

I laugh because I think you're funny.

...I wrote this poem because I observed all this happening.
