Slight over estimate

Given that the landing had completely disappeared under heaps of clothes, games,medical supplies (enough to equip a Red Cross mission) and so on , I decided it was, perhaps, time to start packing . Brought out brand new rucksack and a smaller, older version borrowed( i.e. pinched) from Peter.
Put in walking boots first. They took up at least a quarter of the space. Decided, despite forecast of "very warm" from the met office to travel in boots. In with two pairs pyjamas( one on, one in the wash), assorted undies, three t shirts and a pair of jeans. Also essential Extra Strong Yorkshire tea bags for early morning cuppa in case all Cape Town can offer is that horrible yellow Liptons cat wee stuff. Smugly do up rucksack and turn to smaller one, to be used as hand luggage. In go presents, for the orphanage, the two small children of a friend I plan to visit and the two children sponsored by school. Disaster. Rucksack now full, with no room for Home Stay presents( shortbread with bemused looking highland cattle on tin), mobile charger and file of Essential Documents. Remove one box fuzzy felt and squash in highland cattle. Remember that still haven't put in toilet bag, make up ( yes, non essential I know for true Gap Year Youf, but ladies of a certain age mustn't frighten the natives),book for the journey or raincoat. Scene now of total chaos, reminiscent of the wonderful Jerome K. Jerome "Three men in a Boat" .
The ridiculous thing is, after a few days, all pressies will have been distributed and I'll have virtually nothing for myself....still, an empty rucksack does allow for some serious shopping before the return trip!
Meanwhile, am off to double check luggage allowances.......
