Imagine you are in a shoe shop and are queing in single file. The girl in front of you does not have her purse and to your dismay you then realise you don't have yours either. A solution is that a friend towards the back of the queue is offering to throw her purse towards you, you can not jump the queue until the purse has been thrown to you. Once thrown you can then quickly dodge the girl in front of you, catch the purse and get served.

Would it complicate matters if the girl in front of you was on your team?

She is on your team.

So, bearing in mind that you spelt 'offside' incorrectly, what is your third deliberate mistake?

Not replacing a keyboard early enough.
